MetaInfo: Don't start with an article

[cassidyjames]

One of the Flathub MetaInfo Quality Guidelines Chrome is currently failing is its summary starts with an article. These guidelines should be followed for improved display across Flathub.

This PR reworks the summary, adapting copy from the Chrome app listing for Android while:

• Not repeating the developer name
• Keeping it under 35 characters

Started test build 116432

[flathubbot]

Build 116432 successful
To test this build, install it from the testing repository:

flatpak install --user https://dl.flathub.org/build-repo/99248/com.google.Chrome.flatpakref

Looks goody, but would add 'by Google' or 'from Google'

To clarify the origin of the software.
Should be 35 characters or less.

The summary is not to communicate the developer or origin; that’s precisely what the <developer> (or deprecated <developer_name> as used here) tag is¹. In addition, the <name> already includes Google as well. So we don't need:

Google Chrome
by Google
Fast and easy web browser from Google

I think it’s clear it is from Google. 😅

These files were taken from upstream (ditto for the one in Chromium), are these things that should be pushed up there as well?

[cassidyjames]

@refi64 yeah that's fair; I've not contributed to Chromium so idk if I'll find the time to contribute that but it should definitely go upstream if possible.
