Merge #733: Edit 0.14.1 release notes to separate multiple PRs with "," instead of "/"

98b565a Plugins: update githubify for monotree PR mentions (David A. Harding)
29e6cda Edit 0.14.1 release notes to separate multiple PRs with "," instead of "/" (David A. Harding)

Pull request description:

  As mentioned today in #bitcoin-core-dev IRC, the release notes for 0.21.0 will include at least one reference to a PR that was merged in the new GUI repository.  laanwj said he'll put this in the notes as "gui/#nnnn", so this PR updates the plugin to handle that appropriately.

  To eliminate conflicts, one historic release note is updated to change from using `/` as a separator between PRs to using `,` as the separator.  The comma is consistent with other release notes, such as that for 0.14.0.

  This change should be forward compatible for other possible monotree repos as long as they're part of the bitcoin-core organization and the release notes use the format `<repo-name>/#<pr-number>`, e.g. `wallet/#123`.
