Fix JBang metadata generation to detect all commands

[gnodet]

Summary

• Fix PrepareCamelJBangCommandsMojo to match new CommandLine(this) in addition to new CommandLine(main), and update the subcommand regex accordingly
• This was causing several commands/options to be missing from generated docs and metadata:
  • Missing wrapper command and dataweave subcommand docs
  • Missing bind deprecation notice
  • Wrong description for --skip-plugins option
• Regenerated all affected docs and metadata

Test plan

• Build succeeds with mvn install -B -pl tooling/maven/camel-package-maven-plugin,dsl/camel-jbang/camel-jbang-core -DskipTests
• CI passes
