mobileToDesktop doesn't change the browser name

[ylemkimon]

npx browserslist --mobile-to-desktop ">3%, and_chr 50"

Actual

and_chr 81
and_chr 50
chrome 83
ios_saf 13.4-13.5

Expected

chrome 50
chrome 81
chrome 83
ios_saf 13.4-13.5

Currently, mobileToDesktop logic is only applied to byName:

browserslist/index.js

Lines 245 to 249 in f5ff062

	function byName (name, context) {
	name = name.toLowerCase()
	name = browserslist.aliases[name] || name
	if (context.mobileToDesktop && browserslist.desktopNames[name]) {
	var desktop = browserslist.data[browserslist.desktopNames[name]]

Is this intended behavior?

Nope, let's fix it in pull request

@ai Looking at the code and commits, it turns out mobileToDesktop doesn't change the mobile browser to desktop one like what the doc says and its name suggests, but only resolves the version part using desktop one:

browserslist/index.js

Line 254 in f5ff062

cloned.name = name

I think there are two ways to proceed:

1. Change the browser name if mobileToDesktop is true. This may be a breaking change since it modifies the behavior of an existing option.
2. Add another option, something like normalize, along with Option to return Chrome versions for Chromium-based browsers #508. I think it can take arrays of normalizer names, e.g., mobileToDesktop, chromiumToChrome, or custom functions.

I like new option
