[PATCH] notmuch: Configure mailing list archive links

[Xinglu Chen <public@yoctocell.xyz>]

This adds an entry to `notmuch-show-stash-ml-archive-link-alist` that
reads the `piem-inboxes` variable and returns the public-inbox archive
url.  This means that users don't have to manually add public-inbox
archive urls to `notmuch-show-stash-ml-archive-link-alist`.
---
You can run `notmuch-show-stash-mlarchive-link` on this message, and
paste the link in the browser to see it in action (assuming you have
configured `piem-inboxes`).
