bug(ci): lock-file is part of format check.

[Hweinstock]

Problem

the shrink wrap file is part of the formatting check. This causes regenerating the file to fail the formatter.
Ex.

• chore(deps): bump fflate from 0.8.2 to 0.8.3 #1335
• chore(deps-dev): bump @vitest/coverage-v8 from 4.1.6 to 4.1.8 #1332

To reproduce, run npm shrinkwrap and observe that npm run format:check now fails.

Definition of Done

• exclude shrinkwrap/lock-file from the formatting.
