Related to https://meta.discourse.org/t/host-is-invalid-error-when-tld-is-longer-than-7-characters/46081.
Using Discourse `v2.4.0.beta2 +119`, I can't add an host (when embedding, cf. `/admin/customize/embedding`) ending with `.engineering`.
Turns out current regex limits to 10 characters.
Fix is dumb: it only allows for up to 24 chars, which is the **current** max TLD length, see https://stackoverflow.com/a/22038535/1907212.

Maybe a better (and longer-term) fix would be to allow for up to 64 chars, which I understand comes from the RFC.
I'm not at ease with regexes, so can't be sure about it, but [this suggestion](https://meta.discourse.org/t/host-is-invalid-error-when-tld-is-longer-than-7-characters/46081/8?u=julienma) seems pretty good:
> rules of DNS labels are:
>
> - All labels are 1 to 63 characters, case insensitive A to Z, 0 to 9 and - (hyphen), all from ASCII.
> - No labels may start with a hyphen.
> - No top level domain label may start with a number.
>
>That means a regexp for a valid domain name would look like:
>
>`/^([a-z0-9][a-z0-9-]{0,62}\.)+[a-z][a-z0-9-]{0,62}\.?$/`
>
>Domains that are just a TLD are sufficiently bizarre as to be worth ignoring.
* FIX: Better error when SSO fails due to blank secret
* Update spec/requests/session_controller_spec.rb

When `SiteSetting.embed_truncate` is enabled (by default), the truncated
string is mutatable and does not raise an error.
However, when the setting is disabled, the `contents` string is frozen
and immutable, and will raise a `FrozenError`.
- will ensure this tag is not restricted to another category, and not only ensure this category can use it
- will clean tags param, in case client is sending an empty array, eg: [""], this could be solved client-side, but we ensure it won't happen ever this way
