Functionality of html5_upload has been been merged into core, but has not been added to backdrop_merged_modules()

[indigoxela]

Description of the bug

Follow-up to #440, where multi-upload functionality has finally landed in core. 🎉

But for whatever reason we totally missed to add it to function backdrop_merged_modules() and that would be important, as the module breaks. More specifically - uploading into fields with cardinality > 1 won't work anymore.

Steps To Reproduce

1. Update to Backdrop 1.34.0
2. See the message that the contrib module got disabled
3. Go to admin/modules and try to enable it again

Actual behavior

You can enable it.

Expected behavior

You shouldn't be able to.

Additional information

• Backdrop CMS version: 1.34.0
