Suppress a warning when 'uv' is used instead of 'pip'

[tramora]

• take into account the 'uv' string in the INSTALLER meta-file
• the 'pip' installation method becomes 'pip-uv' as they are quite similar

Fixes #602

The only surprising detail for the user would be seeing 'pip-uv' in the status

khiops local installation settings
version             : 11.0.1
...
install type        : pip-uv

TODO Before Asking for a Review

• Rebase your branch to the latest version of main (or main-v10)
• Make sure all CI workflows are green
• When adding a public feature/fix: Update the Unreleased section of CHANGELOG.md (no date)
• Self-Review: Review "Files Changed" tab and fix any problems you find
• API Docs (only if there are changes in docstrings, rst files or samples):
  • Check the docs build without warning: see the log of the API Docs workflow
  • Check that your changes render well in HTML: download the API Docs artifact and open index.html
  • If there are any problems it is faster to iterate by building locally the API Docs
