Key order in `keys/node.keys` does not match `node/README.md` sort order by first name

[MikeMcC399]

Situation

Running the tool ./update-keys.sh writes the keys in keys/node.keys in the same order that they are listed in the source on nodejs/node > Release keys where they are sorted in order of first name.

This causes a difference:

$ git diff
diff --git a/keys/node.keys b/keys/node.keys
index 3ae5e6b6..a3c92ce2 100644

PR #2551 placed the new key 655F3B5C1FB3FA8D1A0CA6BDE4A7D232B936D2FD for @sxa at the end of the file, and not in the second to last place to conform with the node README.

Running ./update-keys.sh ideally should make no changes if the keys/node.keys is supposed to be up to date.

Suggestion

1. Wait to see if PR chore: switch to official release-keys repo to verify Node.js artefacts #2415 achieves consensus and is landed. In this case keys/node.keys is deleted and the issue is resolved automatically, and for any future changes.
2. If an automated update is not approved and landed, then re-sync the key order.

This is a housekeeping exercise only. The order of the keys in keys/node.keys does not affect their usage when building Docker images.
