[1.12] Delete injector mutating webhook on downgrade from 1.12 to 1.11

[JoshVanL]

If a downgrade is occurring for 1.12 to 1.11, delete the injector mutating webhook so that 1.11 helm chart installs correct CA bundle. Re-create webhook in the event of upgrade failing.

@mukundansundar yes, this PR was intended to improve downgrade support by covering all 1.11 releases, not only those with the helm chart fixes.
