feat: Angular boilerplate

[9kubczas4]

PR includes a basic Angular Hello World boilerplate for Firebase App Hosting.

It shows basic features like:

• SSR
• SSG
• Deferrable Views

@jhuleatt @jamesdaniels please let me know what links should be displayed here.

FWIW the links were removed in the Next.js boilerplate

[jhuleatt]

let's remove the links, but keep the CSS please so we can easily add them back in later.

[jhuleatt]

Looks good to me once links are removed (#174 (comment)).

Seems like CI is failing, is that an easy fix?

[Yuangwang]

Could you add a brief description of what this is for?

[9kubczas4]

@Yuangwang just added a short description to the PR.

[Yuangwang]

Two small comments, but otherwise LGTM once the comments are addressed and CI is fixed

[Yuangwang]

Should this be changed to something else?

I think the nextjs template calls this page "Next.js on Firebase App Hosting" so maybe "Angular on Firebase App Hosting" works

Hi,

It was implemented based on designs.
I'm more than happy to introduce some content changes, but I just wanted to be sure that all of us are on the same page.

+1 to mirror the Next.js h1

firebase-framework-tools/starters/nextjs/basic/src/app/page.tsx

Line 6 in e821aff

<h1 className="heading">Next.js on Firebase App Hosting</h1>

[9kubczas4]

I've applied proposal in recent commit.

[Yuangwang]

I think this should probably be renamed, maybe just SSG is good

[leoortizz]

I changed the Next.js one to just SSG so I think this one can follow

firebase-framework-tools/starters/nextjs/basic/src/app/ssg/page.tsx

Line 6 in e821aff

<h1 className="heading">SSG</h1>

I've applied proposal in recent commit.

updated this PR to get the package lock fix from #173

Hi @Yuangwang,

The build step is failing on CI, locally it works fine.

The following error occurs:

Error: src/firebase-aware.ts(8,17): error TS7016: Could not find a declaration file for module 'lru-cache'. '/home/runner/work/firebase-framework-tools/firebase-framework-tools/node_modules/lru-cache/index.js' implicitly has an 'any' type.
  Try `npm i --save-dev @types/lru-cache` if it exists or add a new declaration (.d.ts) file containing `declare module 'lru-cache';`
Error: src/firebase-aware.ts(23,13): error TS7006: Parameter 'value' implicitly has an 'any' type.
npm ERR! Lifecycle script `build` failed with error:

It looks like it's unrelated to changes in this PR.
