Upgrade trunk + linters

Bumping linter versions to get rid of deprecated downstream dependencies (observed in run output on another CI job)

Notes:

• trunk upgrade now detects the location of the trunk script (in our case stored in the repo) and updates it as well.
• structcheck and a couple other linters are deprecated (no support for generics, and no plan to update them) and covered by deadcode
• I added a second commit of no-op lint fixes for easier review. Can be broken out into another PR if people feel it is necessary.
