Allow users with "can manage" to receive access requests

[mairasalazar]

Describe the bug

When a user is granted "can manage" in a record, the help implies that the user can manage access. However, access requests are not visible to users that can manage the record, only to the owners.

Steps to Reproduce

1. Publish a record with restricted files.
2. In share access -> People, add a user with "can manage" access. In settings, allow users to request access.
3. Create a request to view the files in the record with a third account
4. Record owner sees the request in their dashboard, but manager user does not.

Expected behavior

User with "can manage" access also is able to see and accept/reject access requests

Additional context

Changes probably are needed in invenio-rdm-records/invenio_rdm_records/notifications/builders.py and invenio-rdm-records/invenio_rdm_records/requests/access/requests.py
