tpl/tplimpl: Change resources.GetRemote errors to suppressible warnings #13803
Description
Affects these shortcodes:
tpl/tplimpl/embedded/templates/_shortcodes/twitter.htmltpl/tplimpl/embedded/templates/_shortcodes/twitter_simple.htmltpl/tplimpl/embedded/templates/_shortcodes/x.htmltpl/tplimpl/embedded/templates/_shortcodes/x_simple.htmltpl/tplimpl/embedded/templates/_shortcodes/vimeo_simple.html
We already emit suppressible warnings with 404s. We need to do the same with other errors. This was an oversight when I reworked these shortcodes a few months ago.
