Trim space from age keys

[johanfleury]

Fix a bug where settings keys in .sops.yaml using YAML’s multiline strings results in failed to parse input:

$ cat .sops.yaml
creation_rules:
  - path_regex: \.sops\.yaml$
    encrypted_regex: ^(data|stringData)$
    age: >-
      age1XXX,
      age1YYY
$ sops foo.sops.yaml
failed to parse input as Bech32-encoded age public key: malformed recipient " age1YYY": invalid character human-readable part: s[0]=32

@johanfleury Thanks for the PR! Can you please change it so it will be merged into develop instead of master.

[johanfleury]

Done :)

@johanfleury We just fixed this in #848, but due to making the initial PR against master, tests are not running. Would you mind rebasing against develop or merging mozilla:develop into this branch and pushing up another commit to re-trigger CI?

[johanfleury]

Should be good now :)

Thank you @johanfleury!
