The linter found some issues in viewer.html with </input> which isn't required
and a missing closing div in test/resources/reftest-analyzer.html.
The HTML can now be nicely formatted. In order to not break the build for
mozilla-central, the preprocessor has been fixed in order to take into account
the white spaces at the beginning of a comment line.
And finally, make .prettierrc (which is supposed to be either json or yaml)
itself lintable.
The HTML button elements we use are all regular buttons that don't
submit form data to a server. According to
https://developer.mozilla.org/en-US/docs/Web/HTML/Element/button#notes
those buttons should all have their type set to `button` explicitly, but
we only do that a handful of them. This commit fixes the issue by
consistently giving all our buttons the `button` type.

- Remove the `errorWrapper`-element, since it simplifies the example and is consistent with the default viewer; see PR 15533.
- Simplify the l10n-handling, since the `NullL10n` should be able to translate everything e.g. without fallback values; see PR 17146.
