Went over all generated manual pages and fixed some markdown issues,
mostly escaping "_" to avoid underlining entire paragraphs.

Some textual fixes in route53 and other cloud DNS plugins.

Regenerated the markdown with mmark.

This PR updates go.tidy.yml, and use pseudo name
`coredns-auto-go-mod-tidy[bot]`, so that the commit
is not associated with real user. Otherwise
the commit history could be confusing.

This is similar to what `dependabot[bot]` is doing
for commits generated by bots.
