Looking forwards to seeing this in action, @Mryam1!

One tricky thing about our project template infrastructure is that it's very difficult to get a runnable project from the source code, which complicates the review. Do you have some way of executing these updated templates to get an example of the output project? I totally understand if not, but if it's possible to make a small repo somewhere containing examples of the emitted projects (that are runnable) that would be extremely beneficial.

@SteveSandersonMS Mryam tested each template locally with the template with the project template scripts and will respond to this PR with a few screenshots. She noticed that she couldn't test the Identity UI locally. We tried passing the -au Individual in the scripts, and we get a bunch of errors.

Could @Mryam1 publish the generated projects from scripts directory to a GitHub repo? Might be quicker than having to build the project.

Here is a screenshot of the webapp template running locally with bootstrap5.

What are the steps to doing this? @pranavkm

Merged this branch and continuing this PR in #34052 still working through the issues around identity UI, but I was able to generate current outputs of the templates which don't use auth which can be reviewed already:
