Add GPG key information to the credential inventory

Problem to solve

In 12.6 we introduced the Credentials Inventory to help compliance-minded organizations manage their user's access credentials. Currently, this inventory contains information on PATs and SSH keys. The inventory does not include information about GPG keys that are in use, which can be an additional element of managing credentials in a complex context for customers.

Intended users

• Cameron (Compliance Manager)

User experience goal

Cameron should be able to view GPG key information in the credentials inventory.

Proposal

Add GPG key information to the credential inventory.

Split into three implementation issues:

1. Add the GPG keys list view: #282429 (closed)
2. Add the GPG keys revoke button: #282431
3. Add the GPG keys delete button: #282432
