chore: use dependency-groups for dev (#2287)

# What does this PR do?

The previous `[project.optional-dependencies]` was misrepresenting what
the packages were. They were NOT optional dependencies to the project
but development dependencies. Unlike optional dependencies, development
dependencies are local-only and will not be included in the project
requirements when published to PyPI or other indexes. As such,
development dependencies are not included in the [project] table.
Additionally, the dev group is synced by default.
