Consider Using asdf

[Kurt-von-Laven]

Is your feature request related to a problem? Please describe.
Mega-Linter presently maintains a wide variety of tool installation snippets, but this work is already done by asdf.

Describe the solution you'd like
Use asdf in tandem with .tool-versions files to install all asdf-supported tools. Write asdf plugins for any tools we need to install that don't support asdf.

Describe alternatives you've considered
Leave the code base as is.

Additional context
This change should not affect users of Mega-Linter, only contributors.

Do you mean some unique install command line to run to be able to contribute to Mega-Linter easily on any platform ?

If yes, that's a great idea ! :)

If it affects only contributors, that's great so no risk of regression for users

[Kurt-von-Laven]

Yeah, I think that is a compelling use case for asdf. I could also see it being valuable in Dockerfiles since presently they install a lot of different tools via, for example, curling install scripts that upstream may break. That part would have nonzero regression risk, so it would require more testing, but no reason they would need to be done all at once.
