…-port #15283) (#15369)

* deps: downgrade jruby, keep updated default-gem dependencies (#15283)

forward-ports non-release-branch components of #15283 to `main`

* deps: downgrade jruby, keep updated default-gem dependencies

By downgrading JRuby to 9.4.2.0 we avoid the silent global crash of the
scheduler backing `Concurrent::TimerTask` that occurs when Jruby 9.4.3.0's
invokedynamic promotes a method to run natively, incorrectly.

Upstream bug: jruby/jruby#7904

Along with the downgrade of JRuby itself to 9.4.2.0, we cherry-pick the
updates to gems that were included in the latest JRuby 9.4.3.0 to ensure
we don't back out relevant fixes to stdlib.

We also remove a pinned-dependency on `racc` that is no longer relevant.

Resolves: #15282

* Imported the licenses for some gems

- cgi
- date
- ffi-binary-libfixposix
- io-console
- net-http
- net-protocol
- reline
- time
- timeout
- uri

* specs: avoid mocking global ::Gem::Dependency::new

* build: remove redundanct dependsOn declaration

* deps: notice use of ffi-binary-libfixposix via Ruby license

this gem is tri-licensed `Ruby` / `EPL-2.0` / `LGPL-2.1-or-later` and
the Ruby license is preferred to EPL when available
