Enable DeserializationFeature.READ_ENUMS_USING_TO_STRING by default (3.0)

Implements JSTEP-2 > DeserializationFeature

[JooHyukKim]

Re-running CI because of Fuzzer failure (was nearly impossible to read log, due to its enormous volume)

[JooHyukKim]

Fuzzer is failing at build stage with import error.
Anyone seen this before? 🤔

[cowtowncoder]

I do not recall seeing that error, but I also haven't been paying attention to Fuzzer action.

I think I should just go ahead and disable it, seems to have little value and I think OSS-Fuzz runs their generation elsewhere anyway.

Oddly enough, it runs only for... PRs? And one for jackson-core seems to succeed.
There's one different, wrt permissions, I can try to change that.

[cowtowncoder]

@pjfanning pointed the obvious: Jackson package name means OSS-Fuzz code, built against 2.x, won't work. So this should now be merged, fixed.

[cowtowncoder]

Will review this and #4567 later today, get merged. Good stuff!

[JooHyukKim]

Will update JSTEP-2 Wiki accordingly.
For this PR and one for SerializationFeature
