[Suggestion] Add option to parse sanitized strings

[wyntrr-end]

In some cases, it is nice to be able to pass a string into the description or details or text from a variable, so other steps in a workflow can generate a message and have this action send the message to Discord.
However, as discussed in this article, variables cannot have multiple lines, so if you want to send a multiline string, some standard substitutions must be made. It would be very helpful to have the option to properly send strings like this to Discord, as just sending one of these "sanitized" strings into this action results in a Discord message filled with "%25"s and "%0A"s and "%0D"s instead of the appropriate characters.
