Add missing eslint-config-prettier to ESLint flat config

[mderriey]

What

This is a follow-up to #34 where I forgot to add the eslint-config-prettier config.

Other changes

• Add Dependabot configuration for GitHub Actions.
• Update packages.
• Remove esbuild npm override as new vitest version ships with a fixed esbuild version.

Notes

commander stays on v12 as v13 introduces a breaking change where short options (with a single dash) cannot contain more than a single character, see the changelog for v13.

@mderriey @tristanmenzel Apparently chalk has moved to es module only in v5, which seems to have caused this failure https://github.com/algorandfoundation/algokit-utils-ts/actions/runs/14065836162/job/39389346075#step:14:32

Should we switch back to v4 or handle in some other way? Currently the usage in algokit-utils-ts has been pinned to the previous version.

@neilcampbell I'll have a look at this today.
