Subject: [PATCH] Set GIT_TERMINAL_PROMPT=0 when resolving dependencies

The interactive terminal prompt is not compatible with our TUI spinner
animation, which will shadow the prompt and make it look like uv is
hanging forever.

Interactive auth is still supported via GUI mechanisms configured
through git, like SSH_ASKPASS.

This fixes https://github.com/astral-sh/uv/issues/5107
