We do not use "#bot_table_error" element to show any errors
anymore. It was previously used to show the error if bot
creation failed but since 6db88f0d39 moved bot creation
to a modal, we now show error, if any, inside the modal
itself. This commit also removes the hide_errors function
since the error element itself is removed.
"Add a new bot" tab from personal `settings > bots` moving this
into a modal form, so we can trigger this form from other places
too without duplicating the code.
Fixes part of #20309.
We fixed the main issue of this form in CVE-2020-9444, but the audit
done at that time only included links found in rendered_markdown; this
change completes our audit for links with target=_blank anywhere in
the codebase.
