Feature Reqeust: Add shell command to uv cli

[tleonhardt]

I love how fast uv is and I am beginning to use it as a replacement for pipenv. The one thing I really miss is the ability to do something like uv shell to quickly and easily activate the venv. This could be a very simple command that takes no arguments and just runs source .venv/bin/activate where .venv is the path to the virtual env created by uv.

Thanks! I believe this is the same as #1910 -- you can track that issue instead.
