[feature] Add pager for interactive search of multiple line match and context match

[HerringtonDarkholme]

⭐ Suggestion

ast-grep currently outputs al matches in a detached screen for interactive mode output.

The screen can help us separate different results across files. However, matches in a large file can still be quite overwhelming for one single screen.

Piping the output in a pager will be more readable.
https://docs.rs/minus/latest/minus/index.html looks like a promising library.

💻 Use Cases

Improve readability of printing code around match, multiple line matches, or many matches in one file.
