Enable repo override for `repo deploy-key delete` (cli#5152)

Standardize pager output across commands (cli#5141)

Add pager functionality to the following commands:
- gist list
- pr checks
- release list
- run list
- run view
- secret list
- workflow list
- workflow view

Additionally, normalize error handling when starting the pager has
failed: only print a non-fatal notice to stderr instead of aborting the
whole command.
