feat(instrumentation-koa): Add support for koa 3

[tlindhardt]

Which problem is this PR solving?

• During the upgrade of our project from v2 to v3 I noticed that the span name was not correct and the attributes were missing. Upon further inspection I found that the instrumentation was being skipped entirely.

Short description of the changes

• Switched to ATTR_HTTP_ROUTE from SEMATTRS_HTTP_ROUTE
• Add support to instrumentation-koa for koa v3
• Updated tests
  • This includes removing a test to validate the generator middleware is skipped as that is no longer supported and mentioned in the upgrade guide

I wasn't sure of the release process and if I needed to also change the manifest file or not.

@seemk @JacksonWeber are either of you interested in becoming component owner here?

With this change only v3 and up are going to be tested. So we won't know if this instrumentation is still compatible with the ^2.7.0 range because it wont be tested anymore.

Suggested change

	include: "^3.0.1"
	include: ">=2.7.0 <4"

@tlindhardt

Thanks for contributing to OpenTelemetry. And sorry for getting here after 3 weeks.

I'll have this PR in my radar from now on. Please resolve the conflicts and read my comments

[david-luna]

I sponsor this PR.

[tlindhardt]

@david-luna I went ahead and made the requested changes. I wasn't exactly sure the best way to not run the test in 3.0 but let me know what you think.

Thanks!
