Add notes for action.openPopup API in Firefox

[oliverdunk]

Summary

Updates the compatibility information for the WebExtension action.openPopup API following the changes in https://phabricator.services.mozilla.com/D139796. In particular, Firefox now has support for a windowId parameter and the user gesture requirement has been removed behind a preference currently enabled in Nightly.

I have a similar PR coming to update the main MDN page, which this one is intended to land at the same time as.

Test results and supporting details

Original bug (including windowId support): https://bugzilla.mozilla.org/show_bug.cgi?id=1755763

Removing preference: https://bugzilla.mozilla.org/show_bug.cgi?id=1799344

I've been working on these changes with @Rob--W.

Ideally, I'd just shorten this to "Since Firefox 108, user interaction is no longer required to call this API."

Now, since the pref is required, maybe also ... when the ... pref is set (<a ...>bug xxx</a>).

When the pref is finally flipped, we could do something like this:

browser-compat-data/webextensions/api/identity.json

Lines 63 to 67 in 2687c37

	"notes": [
	"Since Firefox 86, the <code>redirect_url</code> parameter now supports a loopback address, see <a href='https://developer.mozilla.org/docs/Mozilla/Add-ons/WebExtensions/API/identity#getting_the_redirect_url'>Getting the redirect URL</a> for details.",
	"Between Firefox 75 and Firefox 86, the <code>redirect_uri</code> URL parameter must be set to the URL returned by <code>identity.getRedirectURL()</code>.",
	"Between Firefox 63 and Firefox 75, the <code>redirect_uri</code> URL parameter was optional."
	]

... or just keep the minimal simple text from the top of this comment, without any reference to a preference, since the preference (flag) would be irrelevant: https://github.com/mdn/browser-compat-data/blob/main/docs/data-guidelines/index.md#removal-of-irrelevant-flag-data
