Remove bun lock file

[prabhu]

bun container builds were failing. Upon investigation it is clear that bun lock file changes with install and running bun install even without the --frozen-lockfile flag still errors out.

0.391 bun install v1.1.6 (e58d67b4)
0.447  Resolving dependencies
19.63  Resolved, downloaded and extracted [10]
19.65 error: lockfile had changes, but lockfile is frozen
19.65 note: try re-running without --frozen-lockfile and commit the updated lockfile

Removing the lock file helps. But do not use the bun version in production!
