docs(php): Add missing configuration property composerPackageName

[phramz]

PR checklist

• Read the contribution guidelines.
• Pull Request title clearly describes the work in the pull request and Pull Request description provides details about how to validate the work. Missing information here may result in delayed response from the community.
• Run the following to build the project and update samples:

  ./mvnw clean package 
  ./bin/generate-samples.sh
  ./bin/utils/export_docs_generators.sh
  

  Commit all changed files.
  This is important, as CI jobs will verify all generator outputs of your HEAD commit as it would merge with master.
  These must match the expectations made by your contribution.
  You may regenerate an individual generator by passing the relevant config(s) as an argument to the script, for example ./bin/generate-samples.sh bin/configs/java*.
  For Windows users, please run the script in Git BASH.
• In case you are adding a new generator, run the following additional script :

  ./bin/utils/ensure-up-to-date
  

  Commit all changed files.
• File the PR against the correct branch: master (6.3.0) (minor release - breaking changes with fallbacks), 7.0.x (breaking changes without fallbacks)
• If your PR is targeting a particular programming language, @mention the technical committee members, so they are more likely to review the pull request.

looks like it's set via the packageName:

Thank for your reply @wing328!

The methods' (getComposerPackageName()) return-value will only be available in the template if all conditions including the regex are met:
https://github.com/OpenAPITools/openapi-generator/blob/master/modules/openapi-generator/src/main/java/org/openapitools/codegen/languages/AbstractPhpCodegen.java#L213-L215

Due to Github user names might contain upper case letters and the name regex won't match them, it's very likely that you will end up without a name attribute in the composer.json.

You can workaround this issue by explicitly setting the composerPackageName as additional property. Therefor I think it's worth being documented.

If it's a good thing to use Github user/repo as is in the first place is another topic ;)
