Decrypt vaulted variables in yaml files

[davetapley]

• Appends decrypted value after the !vault tag.
• Deletes encrypted string from the DOM.

Try to replicate existing semantics,
but no 'Decrypt' button (because I didn't need it).

See:
https://docs.ansible.com/ansible/latest/user_guide/vault.html#creating-encrypted-variables

@davetapley This doesn't seem to work for me atm; testing with this file (vault password is "test") https://github.com/gwatts/ansible-test/blob/main/keys.yaml

[gwatts]

also I think we'd want to maintain the "decrypt" button semantics so it matches the rest of the extension behavior

@gwatts well that is peculiar, I see the same, I'm glad you tested it, I'll 👀

That's fair. I'll see if I can figure something out.
It's a little awkward because I collapse multiple encrypted lines down to a single one, which is easy enough just deleting DOM nodes and inserting a new one, but going the other way might require some more cleverness.
