Extract IIAB_REMOTE_URL from 1 of 2 places, for both Git repos {iiab, iiab-admin-console} and...

...refine these 3 programs:

• iiab-apps-to-be-installed
• iiab-summary
• iiab-diagnostics

Building on things like:

• Enhancement: Adopt better tagging procedures #3266
  • PR Highlight recent git tags (e.g. "8.0-preview-2" and "v0.5.5.9") in /usr/bin/iiab-summary, iiab-diagnostics etc [and remote URLs, branch names, PR count / commit count since tag...] #3267
  • PR Record branch's actual Git remote (URL) to iiab.ini (in 2 places) + cleaner /usr/bin/iiab-summary when Admin Console is missing #3270
  • PR scripts/iiab-summary: Clarify when PR's are auto-pulled #3280
• PR sudo iiab: Concatenate upstream branch names (e.g. huge-speedup--qa--docs) when auto-pulling PR's iiab-factory#221
  • PR /etc/iiab/pr-list-pulled: Save PR details (~7 columns) iiab-factory#224
  • PR Ask Git to track remote + branch when auto-pulling PR's (--set-upstream) iiab-factory#225
  • PR Ask Git to track remote + branch when auto-pulling PR's (--set-upstream) iiab-factory#226
  • PR Extract each PR title (not body!) to /etc/iiab/pr-list-pulled iiab-factory#227

Quickly tested in quite a number of different ways on Ubuntu Server 22.04 on x86_64 and RasPiOS Lite (64-bit) on RPi 4.

FYI this PR brings together a lot, hopefully in a concise package allowing iiab-summary to be very useful to many more QA People and others (it's also included at the top of iiab-diagnostics now).

So it's possible (maybe?) that git log HEAD^2 -1 --oneline (commit + branch name of PR being tested) might not be needed in the end ?

As these details are now prominently included in /etc/iiab/pr-list-pulled

In any case let's keep an eye on it. And finally if necessary, refactoring can later happen along these lines or similarly:

• PR iiab apps to be installed #3290
