chore(pipelines): Remove pipeline script uv lock files (#322)

### Summary

At this point the lock files are causing more harm than good. When not
regularly updated they contain dependencies out of sync with the
elt-common package. Take s3fs, for example, the script lock files
contained a an old 2025 version of s3fs that worked. However, when
developers tried to install elt-common locally and run the same pipeline
script through python and not uv the lockfile is not used and a broken
version of s3fs was used as it crept into pyproject.toml.

When running the pipeline scripts now it will automatically use the
dependency patterns from elt-common and our current [rest catalog
tests](https://github.com/ISISNeutronMuon/analytics-data-platform/blob/e67979ed5f20001ca37beffffda7c9dd79d68ae7/.github/workflows/rest-catalog-tests.yml)
will then ensure a development setup is not broken.
