Support "baseline" queries

[isker]

These were added to browserslist here https://github.com/browserslist/browserslist/pull/903, released in 4.26.0.

Or, at least note that they are not supported in the readme.

Our current workaround - convert the browserslist config to a simple config with an explitis list of browsers with the minimal versions via browserslist.

const browsers = browserslist(browserslistConfig)
const minBrowserVersion = browsers
	.map((str) => str.split(' '))
	.reduce((minVersion, [browser, version]) => {
		minVersion[browser] = minVersion[browser] ? Math.min(minVersion[browser], parseFloat(version)) : parseFloat(version)
		return minVersion
	}, {})
const targets = Object.entries(minBrowserVersion).map(([browser, version]) => `${browser} >=${version}`).join(',')

It converts a config

defaults
not op_mini all
not dead
Firefox ESR
baseline widely available`

into

and_chr >=141
and_ff >=143
and_qq >=14.9
and_uc >=15.5
android >=141
chrome >=109
edge >=111
firefox >=112
ios_saf >=16.4
kaios >=2.5
op_mob >=80
opera >=121
safari >=16.4
samsung >=27

Just curious, what is blocking you from adding support for this? Anything we can help with on the Baseline side?

I'm busy on something else recently, so I don't have time to do it.

Adding support is not trivial. It requires not only the baseline query support itself, but also the baseline-browser-mapping package port.
