Add HAR files for gh_new_issue and gh_new_pr.

[nedtwigg]

Intro guide!

• npm install
• npm run har:view
  • opens a server that looks like this

The clean is a "clean catch" of the URL in question. The gitcasso has our content-script applied. You can only do the gitcasso if you have a dev server running. The hotreload doesn't seem to work as far as I can tell. (since #20 it now has a button in top-right that triggers a full dev build and refreshes the page)

You can also run a unit test against the captured HTML, note in particular usingHar('gh_pr')

gitcasso/browser-extension/tests/lib/enhancers/github.test.ts

Lines 8 to 23 in 59c96f1

	describe('github', () => {
	usingHar('gh_pr').it('should create the correct spot object', async () => {
	const enhancers = new EnhancerRegistry()
	const textareas = document.querySelectorAll('textarea')
	expect(textareas.length).toBe(2)
	expect(enhancers.tryToEnhance(textareas[0]!)).toBeNull()
	expect(enhancers.tryToEnhance(textareas[1]!)?.spot).toMatchInlineSnapshot(`
	{
	"domain": "github.com",
	"number": 517,
	"slug": "diffplug/selfie",
	"type": "GH_PR_ADD_COMMENT",
	"unique_key": "github.com:diffplug/selfie:517",
	}
	`)
	})

• for detection, I would think that the unit tests might be an easier way to test
• npm run har:view hopefully makes the edit/refresh cycle less painful for graphical fidelity
  • could def be a lot better Improve har:view refresh cycle #16
