Intended to be run from nightly Cirrus cron job.
1) Queries github for highest-sorting (not necessarily "latest") tag
2) Checks that the Windows MSI exists, fails if not
3) Cross-checks markdown files to ensure they have up-to-date links
When run interactively, it will auto-update the .md files
to show and link to the latest version. This makes it easy
for anyone to then submit an update PR.
And, it turns out that MSI is obsolete, the new thing is EXE.
Update the tutorials to reflect that.
