🔨 Add script to extract changelog entries by version

[Copilot]

Add bash script to parse CHANGELOG.md files and extract content for a specific version, enabling automated changelog retrieval across packages.

Implementation

• Script: .github/scripts/extract-changelog.sh
• Arguments: <package-dir> <version> (e.g., fast-check 4.5.2, ava 2.0.2)
• Output: Changelog section for specified version, from version header through Features/Fixes sections
• Termination: Stops at next version header or --- separator

Usage

.github/scripts/extract-changelog.sh fast-check 4.5.2
# Outputs:
# # 4.5.2
# 
# _Attach tarballs to GitHub releases_
# [[Code]...][[Diff]...]
# 
# ## Fixes
# ...

.github/scripts/extract-changelog.sh ava 2.0.2

Error Handling

• Missing CHANGELOG.md: exits with code 1
• Version not found: exits with code 1
• Invalid arguments: shows usage message

Works with all packages: fast-check, ava, vitest, jest, worker, expect-type, poisoning, packaged.

Original prompt

bash script that given a version will parse the changelog files and print the part for this version. the script should be given the directory of the considered package (fast-check for fast-check, ava for fast-check/ava...)
