Drop Java 11 requirement brought in by misk

[timtebeek]

Copied over the generated templates and removed the misk dependency to remove the runtime requirement on Java 11+.

• Fixes rewrite-micrometer has a runtime requirement of Java 11 #12

This then allows the Micrometer recipes to be included with our Spring Boot migrations again, as seen on

• Add Micrometer 1.13.x upgrade to Spring Boot 3.3.x migration rewrite-spring#551

Notably we still retain the rewrite-templating dependency and use of Semantics.expression on these lines using micrometer only:

rewrite-micrometer/src/main/java/org/openrewrite/micrometer/misk/MigrateEmptyLabelMiskCounter.java

Lines 71 to 74 in a1aa9a1

	m = expression(
	this, "micrometerCounter",
	(String name, String help) -> Counter.builder(name).description(help).register(Metrics.globalRegistry)
	).build().apply(getCursor(),

The trade off here is a little more maintenance burden on that one NoExplicitEmptyLabelList recipe, for the benefit of having micrometer migration recipes be part of our Spring Boot upgrades again. I think that's valid enough to proceed.
