UV Pip Compile increase test coverage

[albertferras-vrf]

Changes:

• New uv_pip_compile_file_updater_spec.rb to test everything that was tested with pip-tool's pip-compile command. Reviewed tests one by one and either deleted them or adapted it. (See notes below)
• Bump uv to latest version. Tests need minimum 0.2.34 because it adds support for --no-binary
• New uv_pip_compile_options_from_compiled_file because some options' default are different (--skip-extras, --allow-safe and --emit-build-options). Separate methods make it easier to maintain uv and pipcompile versions.

Notes:
Tests removed:

• Incompatible versions. These tests used requirements.txt with —resolver legacy which does not apply to uv. Without the legacy resolver override there is no error on pip-compile or uv pip compile.
• All tests using --resolver options
• Tests using custom headers that include stuff like make upgrade. These are not relevant for uv pip compile mode
• Editable dependencies (-e giturl). As of now, uv does not support VCS Urls in editable dependencies. See Support for editable dependencies with URLs astral-sh/uv#5442

Some differences/changes:

• "Via setup": uv outputs -e . and pip compile -e [file://somepath/dependabot_xxxx] (file://somepath/dependabot_xxxx%60) in the temporary file. The updated requirements.txt does not change though
• “Unsafe dependencies” (pip and setuptools packages) are removed by pip-compile by default, but on the next major release they will no longer remove those by default (—allow-unsafe as new default). Changed the test to check that uv actually includes setuptools, unlike the current pip-compile. See more at uv pip compile adds setuptools (and pip) to requirements.txt astral-sh/uv#1353

We should add your comments to the other pr in dependabot
