Switch from pip to uv

[felipecrs]

Describe what you are trying to accomplish and why in non technical terms
I ran the devcontainer today, and it took several minutes to build. Most of the time was spent installing pip packages.

Describe the solution you'd like
Like Home Assistant switched from pip to uv and it sped up a lot its build process, Frigate should be able to switch too and leverage it. I think uv is one of the best things that ever happened to Python's ecosystem.

Describe alternatives you've considered
There are several alternatives to uv, like poetry, but it's not even closer in terms of speed.

Additional context
