[2.0] Remove old deprecated JVM-scripts

[loicmathieu]

Remove the following tasks that have been deprecated for some time:

• io.kestra.plugin.scripts.groovy.Eval
• io.kestra.plugin.scripts.groovy.FileTransform
• io.kestra.plugin.scripts.nashorn.Eval
• io.kestra.plugin.scripts.nashorn.FileTransform
• io.kestra.plugin.scripts.jython.Eval
• io.kestra.plugin.scripts.jython.FileTransform

The removal should be done for 2.0.

Hey , @loicmathieu @Ben8t I would like to work on this task .

[loicmathieu]

@suraj-0628 we postponed this up until the last miles of 2.0 development sprint so: not now

[suraj-0628]

@loicmathieu Got it 👍🏻

To be done once kestraVersion will be bumped to 2.0.0 when 1.3 won't be an LTS anymore.

[loicmathieu]

This is annoying as we don't want to support them and include them anymore as they are not performant and a security risk.
They should have been removed inside 2.0, we took the decision years ago, as 2.0 already ship better to remove them in 2.1.

Anyway for now min kestraVersion is a 1.3.x for plugin-scripts:

So I just linked this as a sub issue for the 2.0 compatibility EPIC. We chose to bump plugins to kestraVersion 2.0.0:

• when mandatory because related to a non backportable fix on the core
• when 1.3 won't be an LTS anymore
