This is causing the lockfileVersion to change from 1 to 2, which I had to undo before in #6713. It makes sense that it would do this given that the .nvmrc has LTS, and Node v16 is now LTS. But neither WordPress core nor Gutenberg have seemingly updated to Node v16 even though they're on LTS, so their lockfileVersions are still at 1. Looks like this was going to be done in Gutenberg via WordPress/gutenberg#33892 but it was halted to do the same time as WP core in v5.9.

Maybe this is all that is required:
