Support asciicast files as new markup (#22448)

Browse source 
Support [asciicast
files](https://github.com/asciinema/asciinema/blob/develop/doc/asciicast-v2.md)
as a new markup via
[asciinema-player](https://github.com/asciinema/asciinema-player). For
more on asciinema, see the [introduction](https://asciinema.org/).

So users can use asciinema recorder to generate an asciicast file (or
you can download a sample file from
https://asciinema.org/a/335480.cast?dl=1), then upload it to Gitea and
play it on Gitea.

Known issue:

Don't support the [v1 version asciicast
files](https://github.com/asciinema/asciinema/blob/develop/doc/asciicast-v1.md),
it's a poorly designed version, it does not specify the file extension
and uses `*.json` usually, so it's impossible to recognize the files.
