Depends on inveniosoftware/invenio-pages#98 so tests will fail!

[slint]

LGTM, requires a bump in setup.cfg to >=6.0.0,<7.0.0

⚠️⚠️

Good to release, as a "major" bump (i.e. bumping the bX part of the tag)

@wgresshoff could you rebase this one?

[wgresshoff]

@tmorrell I did, but there are still problems (dependency resolution fails because invenio-collections and invenio-banner require different versions from invenio-administration).

[tmorrell]

@utnapischtim will combine this PR with the other dependency bumps in #3050

[tmorrell]

Merged with #3050
