Document ground air start feature

[Valastiri]

Documenting the following feature from A32NX:

• feat(bleed): Ground air start aircraft#8240

[Maximilian-Reuter]

Ha I was just about to ask about documentation regarding this

[Valastiri]

@Maximilian-Reuter just keeping myself posted -- let me know when things are ready -- most I'd ask for help with is just a screenshot of the EFB with the Air Start and any other changed page // similar to what we have already cuz that will 100% need updating aside from any text

[Maximilian-Reuter]

I have added a screenshot to the PR which should be usable for the documentation.
Someone would probably also need to handle the added localization string

[Maximilian-Reuter]

PR is pretty much ready for release
I would suggest a ground air start procedure entry like for crossbleed starts already exists
Speaking of, this page would also need updates: https://docs.flybywiresim.com/pilots-corner/advanced-guides/engines/crossbleed-start/

I also updated the EFB image in my PR since I changed the Icon

Sorry been incredibly busy I see the Discord post as well will look into it
