fix: missing bun.lock (vercel#9958)

### Description

In vercel#9950 (comment)
it was observed that `bun.lock` is missing from this list.

I started by exposing and then consuming the constants right from the
source (d9ea60f) and then added
`bun.lock` to the list in (c5840db)

### Testing Instructions

`bun.lock` should now invalidate. With
vercel#9783 being released, this is
expected behavior.
