Description of problem:

The "seeded" keyword has never been used for flatpak remotes and the "organization_id" does not make sense for search since the taxonomy organization overrides it anyway. They could be removed from the search bar proposals.

How reproducible:

always

Is this issue a regression from an earlier version:

no

Steps to Reproduce:

1. In UI navigate to Content > Flatpak Remotes

2. Click the search bar on the top.

Actual behavior:
"seeded" and "organization_id" keywords are proposed (among others).

Expected behavior:

They shouldn't be needed.
