Link browser bugs for relative color support

[foolip]

Partial implementation and notes is used for a bunch of the relative_syntax entries, from https://github.com/mdn/browser-compat-data/pull/21937.

I've sent https://github.com/mdn/browser-compat-data/pull/22960 for two notes I suspect are wrong. These are the remaining notes that should ideally have a bug link so that it's possible to check if it's resolved or not:

color() in Safari:

https://github.com/mdn/browser-compat-data/blob/712e11aa4181a6c92aa552690c93e0354038b705/css/types/color.json#L148-L152

HSL in Chrome and Safari:

https://github.com/mdn/browser-compat-data/blob/712e11aa4181a6c92aa552690c93e0354038b705/css/types/color.json#L401-L405

HWB in Chrome and Safari:

https://github.com/mdn/browser-compat-data/blob/712e11aa4181a6c92aa552690c93e0354038b705/css/types/color.json#L543-L547

LCH in Safari:

https://github.com/mdn/browser-compat-data/blob/712e11aa4181a6c92aa552690c93e0354038b705/css/types/color.json#L784-L788

Oklch in Safari:

https://github.com/mdn/browser-compat-data/blob/712e11aa4181a6c92aa552690c93e0354038b705/css/types/color.json#L1128-L1132

@romainmenke do you have bug links handy for any of these? Are there any you know to be fixed already?

[romainmenke]

For Safari I do not have any bug links.

For Chrome only HSL/HWB seems to be still open. This issue seems relevant : https://issues.chromium.org/issues/41488645

I don't know exactly when this was fixed.

Chrome 124 is still broken, 126 seems fine.

Yeah, it seems fixed in Chrome 125, both HSL and HWB.
