Cosign verify updates
Merge Request Description
Related to https://repo1.dso.mil/platform-one/private/big-bang/ironbank/ironbank-bootstrap/-/issues/1316
updates:
- allow for either a public key or certs. (we'll probably never use certs over the public key but we needed it during testing and decided to leave it as it puts this function more inline with the actual cosign cli.)
- use file path instead of string
