uv should have commands to manage and/or display the version of the current project

In CD workflows, it's handy to have a tool that can read and write the version of the project in its pyproject.toml file.

For example, poetry version (with no arguments) prints the project's version (in one of a few formats), and poetry version x.y.z updates the pyproject.toml file and sets tool.poetry.version = x.y.z.

I use both of these features in Harlequin's CD workflows, first to set the version from the release branch name, and then to create a GitHub release after the package is published. I would love to use uv instead.

(Poetry also includes a feature to bump the version based on a "bump rule" like minor, but I don't use that feature personally).

Today uv version and uv --version both display uv's version, not the project version.

This feature is similar to #5975 , and might be a subcommand of uv info or uv show (or uv project): uv info version --short etc. For CD use cases, it's important that the version number is easy to extract from the output.

In brief, we want to support this.

Sorry about the dupe. I searched and couldn't find it
