feat(securefile): Ability to Update existing files

Jackrequested to merge
gitlab-community/gitlab-org/cli:feature/8381/securefile-update into main

Description

Adds the ability to update existing securefiles, removing the need to run numerous commands to get to the same outcome, significantly improving the UX of securefiles when using the CLI

Old way: glab securefile list -> Get ID -> glab securefile remove <id> -> glab securefile create <name> <path>

New way: glab securefile update <name> <path>

Resolves #8381 (closed)

Relates to #8380 (closed) (reuse a helper and extends to avoid code duplication)

How has this been tested?

  • Added unit-tests
  • Tested locally by running
    • glab securefile create jack-test file.txt -R <repo>
    • glab securefile list -R <repo> - To get the checksum
    • Made an edit to the contents of the file i had locally, then ran glab securefile update jack-test file.txt -R <repo> (prompted for confirmation)
    • glab securefile list -R <repo> - Validate checksum has changed (it did)
