BUILD-8999

Removing filter from git fetch.

Unshallow is needed.
Only removing --filter=blob:none should work according to your comments on the Jira ticket. This filter is only an optimization to speed the download time.

I don't see why we need unshallow. I have ran a test against this PR here https://github.com/SonarSource/ops-releasability/actions/runs/17458692819/job/49578097952?pr=473 and it working fine.

🤖 Pull Request summary

Removes --filter=blob:none flag from git fetch operations across build scripts.

• Modifies git_fetch_unshallow() function in Maven, npm, Poetry, and Yarn build scripts
• Updates corresponding unit tests to match the new git fetch commands
• Adds missing function comment in Poetry build script

Review focus: Consider the performance impact of removing the blob filter - this will now download full git objects instead of just references, potentially increasing build times and network usage.
