Support asciicast files as new markup (#22448)
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. Snapshots: <details> ## Upload asciicast files <img width="1134" alt="image" src="https://user-images.githubusercontent.com/9418365/212461061-cc2c7181-0e14-4534-af55-1ec60a639fd1.png"> ## Open an asciicast file <img width="1137" alt="image" src="https://user-images.githubusercontent.com/9418365/212461090-a3b5141f-4894-430d-a2b4-ea257801a0ed.png"> ## Play it <img width="1144" alt="image" src="https://user-images.githubusercontent.com/9418365/212461157-4e82db69-0e41-471d-928f-ac1fe0737105.png"> ## Copy contents from the "video" <img width="1145" alt="image" src="https://user-images.githubusercontent.com/9418365/212461286-211612bc-15d6-427a-89a9-6abff5c6a0a5.png"> ## View the source <img width="1140" alt="image" src="https://user-images.githubusercontent.com/9418365/212461187-05473b2d-ba3d-4072-84a6-4aa1e7d82182.png"> </details> 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.
