feat(ci): Better dependabot grouping

[gregfurman]

Description

Optimizes dependabot groupings to include all deps within the cli/template sections, which need to be bumped to the latest hatchet sdk version.

Also, we need to support uv ecosystems and tighten up unnecessary groupings.

Type of change

• CI (any automation pipeline changes)

What's Changed

• Groups together all SDK example updates into a single PR using multi-ecosystem groupings.
• Ensures we also update uv lockfile for python version bumps.
• Removes refs to non-existent directories & ensures we only target sdks/**/examples instead of the autogenerated examples/**
• Correctly updates all cli template types for each ecosystem (including bun, uv, etc.)

Nice work on this, Greg. I reviewed this in the context of some quickstart and template work I have in progress.

From my review, once this PR merges, Go remains the only uncovered CLI template because it uses go.mod.embed, which Dependabot cannot find given the current logic in the file fetcher. I would be happy to address that in a follow-up PR.

This PR looks good to me @grutt.

@gregfurman #4087 is the follow-up PR for the remaining Go CLI template dependency update issue caused by go.mod.embed.
