#480: Align CI Ruby version between codecov.yml and rake.yml

[VasilevNStas]

Description

codecov.yml uses Ruby 4.0.5 while rake.yml (the primary CI workflow) uses Ruby 3.3. The gemspec requires >=3.3, meaning 3.3 is the minimum supported version.

This drift means coverage is measured on a different Ruby version than the tests run on, which can lead to inconsistencies.

Fix

Changed codecov.yml Ruby version from 4.0.5 to 3.3 to match the rake.yml CI matrix.

Verification

• yamllint — passes
• Ruby YAML.load_file — valid

Closes #480

[edmoffo]

Aligns .github/workflows/codecov.yml to Ruby 3.3, matching rake.yml and the floor declared in fbe.gemspec and README.md. Resolves #480.

Drop the unrelated downgrade of crate-ci/typos from v1.47.1 to v1.47.0 in .github/workflows/typos.yml; it does not belong in this fix.

[kreinba]

Aligns codecov.yml with the rake.yml matrix at 3.3, which also matches the >=3.3 requirement in the gemspec. Closes the drift described in #480.

@kreinba Hey! Nice work on the review 👍 You scored +6 points this time: started with +18 as the base reward, but lost -8 for having zero comments (our policy encourages at least 9 comments to avoid the -5 penalty), and another -4 for the low hit-of-code count of just 2 (we deduct points when it's under 24). Your running total is now +1439 - keep up the momentum and don't forget to check your Zerocracy account for updates!

@edmoffo Thanks for the review! You've earned +6 points for this contribution: +18 as a basis, -8 for absolutely no comments posted during the review, and -4 for too few hits-of-code (only 2, which is below the 24 minimum). Your running score is +1555; don't forget to check your Zerocracy account too.
