chore: Biome linting with auto-fixes [DT-7060]

[lanesawyer]

What

• Runs auto fixes for Biome linting rules
• Turns on lint command in CI (but we won't have it blocking merges, since there are still about 49 errors to resolve)

How

• pnpm lint:fix
• Add the lint command to the placeholder linting CI job we had

@crispipear @Jarbuckle I ran autofixes for these. Biome has "unsafe auto-fixes" and I did not run those. So theoretically, all these changes are good to go, since they only apply the ones that are universally safe.

OME-Zarr and DZI examples are working as expected; approved!
