chore(deps): update fs-extra to 11.3.6 across all packages

[X-Guardian]

Description

Bumps fs-extra to 11.3.6 (and @types/fs-extra to 11.0.4) in every package that depends on it, so the whole monorepo resolves a single copy of each.

Before this change the versions were inconsistent: five packages were already on the 11.x line (11.3.4 / ^11.3.0), while three — @cdktn/provider-generator, @cdktn/cli-core, and cdktn-cli — plus the standalone test/ harness were still pinned to fs-extra@8.1.0 / @types/fs-extra@8.1.5. This aligns all of them on the current release.

Packages updated:

Package	fs-extra	@types/fs-extra
@cdktn/provider-generator	8.1.0 → 11.3.6	8.1.5 → 11.0.4
@cdktn/cli-core	8.1.0 → 11.3.6	8.1.5 → 11.0.4
cdktn-cli	8.1.0 → 11.3.6	8.1.5 → 11.0.4
test/ (non-workspace)	^8.1.0 → ^11.3.6	^8.1.5 → ^11.0.4
@cdktn/provider-schema	11.3.4 → 11.3.6	11.0.4 (unchanged)
@cdktn/commons	11.3.4 → 11.3.6	11.0.4 (unchanged)
@cdktn/hcl2cdk	11.3.4 → 11.3.6	11.0.4 (unchanged)
@cdktn/hcl2json	11.3.4 → 11.3.6	11.0.4 (unchanged)
@cdktn/hcl-tools	^11.3.0 → ^11.3.6	11.0.4 (unchanged)

Two source changes were required. The three packages crossing the 8.x → 11.x boundary were checked against the fs-extra breaking changes in that window. The @types/fs-extra@11 typings are stricter than @types/fs-extra@8 and flagged two existing calls that passed a recursive option to a copy — fs.copy/fs.copySync are always recursive, so recursive was never a valid CopyOptions/CopyOptionsSync key; the looser v8 typings silently accepted it. Removing it is a no-op at runtime:

• @cdktn/provider-generator/src/get/constructs-maker.ts — error TS2769 on fs.copy(source, target, { recursive: true, overwrite: false }) → fs.copy(source, target, { overwrite: false }).
• cdktn-cli/src/bin/cmds/helper/init.ts — error TS2353 on fs.copySync(src, dest, { recursive: true }) → fs.copySync(src, dest).

No behavioural change was needed for the other differences. move() defaulting to overwrite: false from v9 onward doesn't affect the three fs.move call sites in the same file, which already pass { overwrite: true } explicitly. Every other method used across these packages (existsSync, readFile(Sync), writeFile(Sync), remove(Sync), pathExists, mkdirp/mkdirs, copy(Sync), stat, readJson(Sync), appendFileSync, rmSync, unlinkSync, accessSync, constants) is unchanged from 8 through 11. The rest of the 8→11 range only dropped support for Node.js < 14, which the repo already requires.
