Fixes Dockerfile to use uv

[matthewdeanmartin]

Dockerfile had setup.py syntax. Now matches readme.rst

This now works as promised
docker build -t bagit:latest . && docker run -it bagit:latest

I think this would improve caching and also has the ever popular version pin:

Suggested change

	RUN pip install --upgrade pip && pip install uv && uv sync --all-extras
	COPY --from=ghcr.io/astral-sh/uv:0.11.5-python3.14-trixie /uv /uvx /usr/bin/
	ENV UV_LINK_MODE=copy
	RUN --mount=type=cache,target=/root/.cache/uv uv sync --all-extras

(at this point, however, it'd also be reasonable ask whether the base image should simply be FROM ghcr.io/astral-sh/uv:0.11.5-python3.14-trixie)

If we wanted to stay with pip—which has a certain appeal for avoiding various political debates in the community—I would do this:

Suggested change

	RUN pip install --upgrade pip && pip install uv && uv sync --all-extras
	RUN pip install ---upgrade --uploaded-prior-to=$(date -Iseconds --date="1 week ago") pip

It was easier to get it to work with astral-sh/uv:0.11.5-python3.14-trixie

Also added dos2linux because git corrupts the line feeds. I figure if someone is running on linux they probably are running their tests on bare metal, it's the windows people that needs the docker file.
