Remove forward-slash escape (#486)
This was based off of the OWASP XSS prevention cheat sheet --
https://cheatsheetseries.owasp.org/cheatsheets/Cross_Site_Scripting_Prevention_Cheat_Sheet.html#output-encoding-rules-summary
However, there isn't really any attack vector based on forward slash alone, and
it's being removed in the next version of that document.
> There is no proof that escaping forward slash will improve
> defense against XSS, if all other special characters are escaped
> properly, but it forces developers to use non-standard implementation of
> the HTML escaping, what increases the risk of the mistake and makes the
> implementation harder.
