Clarify browsers list for config.toml

When adding or updating the list of browsers in config.toml it’s not always clear to me which browser is which.

Can we add a table in the contributing guidelines with a mapping between the expected values for config.toml vs. naming from MDN and Caniuse?

Something like this :

	config.toml	MDN	caniuse	browserslist
WebView Android	android	webview_android	Android Browser	Android
BlackBerry	bb	?	?	BlackBerry or bb
Chrome	chrome	chrome	Chrome	Chrome
Edge	edge	edge	Edge	Edge
edge_mob	edge_mob	?	?	?
Mozilla Firefox	firefox	firefox	Firefox	Firefox or ff
iOS Safari	ios_saf	safari_ios	iOS Safari	iOS or ios_saf
Internet Explorer	ie	ie	IE	Explorer or ie
Internet Explorer Mobile	ie_mob	?	?	ExplorerMobile or ie_mob
Opera	opera	opera	Opera	Opera
Opera Mini	op_mini	?	?	OperaMini or op_mini
Safari	safari	safari	Safari	Safari
Firefox Android	firefox_mob	firefox_android	Firefox for Android	FirefoxAndroid or and_ff
Samsung Internet	samsung_mob	samsunginternet_android	Samsung Internet	Samsung

notes :

• android does not include later chromium based versions.
• edge does not include later chromium based versions.
• The significant version should be used 103 for chrome and 10.1 for Safari. Safari, iOS and Samsung Internet use major.minor as the significant version.
• Stats for iOS records the OS version, not the browser version

@cdaringe our user-agent normaliser converts android chrome to chrome - if I remember correctly, android chrome and desktop chrome have the same feature set which is why we use chrome for them both.

Our android distinction is for the default android webview that was used and didn’t have the same feature set as chrome

Hehe, yeah that was just an example of what the table could look like. I should have clarified that 😃
