fixed install links

[evensure]

removed "installation/" from each path as the file is located in installation/ already

Maintainer review (advisory — merge authority stays with @marcelfolaron / @broskees)

Intent: Fixes broken relative links in installation/installation-types.md by dropping the redundant installation/ path prefix, since the file already lives in installation/.

Change requests:

1. Verify against the docs router's link resolution before merge. The change assumes links resolve relative to the current file's directory:
   • installation/installation-types.md:5-7 — package-installation.md, docker.md, other-methods.md ✔ (relative-to-file)
     The old installation/installation-types.md-style paths would only work if the site root is the docsify/base root. Please confirm which base the docs site uses (docsify typically resolves relative to the served root, not the file) — if it's root-relative, the correct fix may instead be a leading /installation/.... Merge whichever matches the live site.
2. Confirm the three target files (package-installation.md, docker.md, other-methods.md) all exist in installation/ so none of the three links 404 after the change.

Acceptance checklist (must pass before merge):

1. All three links click through correctly on the rendered/served docs site (manual test — open each link).
2. Link style is consistent with how other in-installation/ pages cross-link (relative-to-file vs root-relative).
3. CLA signed / green (first-time contributor).

CI status: No automated link-checker gate present in this repo. Treat "all three links resolve on the built site" as the manual test gate — this is the one thing to verify since a wrong base assumption would trade three working-in-one-context links for three broken-in-another.

Recommendation: adding a CI link-check (e.g. lychee / markdown-link-check) to this repo would catch exactly this class of PR automatically going forward.

Maintainer review — status: ready (advisory) · priority: P3 · next action: verify link targets, then maintainer merge · owner: @marcelfolaron

1. Intent: Fixes broken relative links in installation/installation-types.md by removing the redundant installation/ path segment (the file already lives in installation/, so the old links resolved to installation/installation/...).

2. Change requests:

• Verify before merge (correctness): the three rewritten links at installation/installation-types.md:5-7 assume sibling files exist in the same dir:

  -- [Package based installation](installation/package-installation.md)
  -- [Docker based installation](installation/docker.md)
  -- [Other](installation/other-methods.md)
  +- [Package based installation](package-installation.md)
  +- [Docker based installation](docker.md)
  +- [Other](other-methods.md)

  docker.md definitely exists (it's edited in Fix typo in Docker installation documentation #48). Please confirm package-installation.md and other-methods.md also exist in installation/ — if the actual filenames differ, these links would still 404. The fix direction is correct regardless.
• No other changes needed; this is the right way to fix the double-prefix.

3. Acceptance checklist (must pass before merge):

• package-installation.md and other-methods.md confirmed present in installation/
• Docs build/link-check CI green (a link checker would catch any remaining 404)
• No behavior change — docs-only, no test required

4. CI status: Not readable through my current tooling — confirm green in the UI. If docs CI includes a link checker, that check passing is the real acceptance gate for this one.
