Mention convenient uv commands for installing esphome from git

[shvmm]

Instead of meddling with pip's --no-deps and --force-reinstall flags,
Users can just do uv pip install git+https://github.com/username/esphome.git@branch --system
And it'd take care of everything automagically.

Output on my Win11 machine:

PS C:\Users\Shvm> uv pip install git+https://github.com/esphome/esphome.git@dev --system
