defaultReleaseBranch is confusing.

[drskur]

This is sample code from nx-monorepo document

const project = new nx_monorepo.NxMonorepoProject({
  defaultReleaseBranch: "main",
  deps: ["aws-cdk-lib", "constructs", "cdk-nag"],
  devDeps: ["aws-prototyping-sdk"],
  name: "my-package",
});

new PDKPipelineTsProject({
  parent: project,
  outdir: "packages/cicd",
  defaultReleaseBranch: "mainline",
  name: "cicd",
  cdkVersion: "2.1.0"
});

I am confusing there are two defaultReleaseBranch properties. And only property of PDKPipelineTsProject seems to work.
Perhaps the code above will trigger the pipeline once the code is pushed to the mainline branch.

And I found that default value of defaultReleaseBranch is "mainline". It is also confusing.
Following code also will trigger the pipeline once the code is pushed to the mainline branch.

const project = new nx_monorepo.NxMonorepoProject({
  defaultReleaseBranch: "main",
  deps: ["aws-cdk-lib", "constructs", "cdk-nag"],
  devDeps: ["aws-prototyping-sdk"],
  name: "my-package",
});

new PDKPipelineTsProject({
  parent: project,
  outdir: "packages/cicd",
  name: "cicd",
  cdkVersion: "2.1.0"
});

So my idea is

1. remove defaultReleaseBranch on the NxMonorepoProject
2. change default value of defaultReleaseBranch in PDKPipelineTsProject to "main"
