[2.10] Fix various sanity errors in plugins (#72168)

* Fix various sanity errors in plugins (#71736)

* Fix various sanity errors in plugins.

* Revert callback_type -> type transform.

* Undo paramiko_ssh 'connection' change, since this discrepancy is hardcoded in the plugin loader.

* Standardize on name and type (for callbacks).

* Fix existing author entries.

* Add 'Unknown (!UNKNOWN)' as author when author is missing.

* These are actually parsed as integers in the code.

* Revert "Add 'Unknown (!UNKNOWN)' as author when author is missing."

This reverts commit 29d1438aca4cb1988ac81c9f6cb3c4e0403b5fae.

(cherry picked from commit aff78f4cbc9a1afe70ca447e17e4c99582ad16b3)

* Undo potentially disrupting normalizations.

* Add changelog fragment for #71736. (#72323)

(cherry picked from commit 0b2b82c0b6eb6466c18cd6feea2222ec756b8f48)
