follow-up: Unlock rollup version

[elboletaire]

This is a follow-up of issue #141. Since the problem is with a specific rollup version, that version has been fixed and this issue is to keep track of the upstream rollup bug, see rollup/rollup#4945

Once the issue is fixed, unlock the fixed version (aka revert PR #142).

Theoretically, this was reverted in upstream... so we should be able to unlock the version and build without issues (at least until they finally merge those changes, but I guess since they now have track of it, it shouldn't happen again).

I'll try to see if we can unlock it during these days.
