NbLaunchDelegate fix and test multi line texts in suite.py

[jtulach]

I cannot open graal/sdk project anymore. Turns out that now its suite.py is using multiline texts and the conversion of suite.py to JSON fails to convert that properly. This PR provides a test and a fix to handle such conversion properly. With the fix I am able to open sdk as well as truffle project without errors.

This fix affects NetBeans IDE, VSCode extension and IGV. CCing @rschatz, @gilles-duboscq

While writing my Enso code, I was surprised I cannot find EnsoDataObject in the lookup. 8838cff fixes that.

this looks like it needs the LSP [ci] enable Language Server Protocol tests and MX [ci] enable "build tools" tests tests?

Ops. Sorry for the mistake.

I guess I got confused with CI & labels. Everything was green,

but I probably used labels incorrectly. I'll do my best to be more careful next time.

Thanks for merging the revert @jtulach

Two things to be aware :

1. When you force pushed to this it started a new set of tests based on the labels that had been set. These had not completed when this was merged.
2. Adding labels by itself does not trigger tests to run again, unfortunately. Pushing to a PR does. And the "hidden" switch to rerun tests with new labels is to lock and unlock conversation (in case you're wondering about why I did this on ActionProvider and its Lookup in NbLaunchDelegate #7059 )

this page on the wiki is explaining a bit how the CI pipeline works:
https://cwiki.apache.org/confluence/display/NETBEANS/PRs+and+You+-+A+reviewer+Guide
the "Important" section mentions some details how the labels are taken into account and when the workflow sees changes.

I think this PR might have been fine if CI would have finished running after the second sync. There is actually an option to enforce "green checks" before gh allows the merge. But last time when we considered to enable that, there were concerns that this could lock us out as far as I remember. (although I think there would be enough tricks left to get around that lockout and unblock it again)
