[MightyCreak]

Add ignore option consecutive-duplicates-with-same-prefixless-values
to rule consecutive-duplicates-with-same-prefixless-values.

Which issue, if any, is this issue related to?

Closes #5607

Is there anything in the PR that needs further explanation?

No, it's pretty self-explanatory I think, but it's the first time I contribute to stylelint and to any JS project, so bare with me please 😉

@MightyCreak Thanks for the pull request. It's looking good so far.

I've requested a change.

This option has the scope to be much broader, e.g. the following should be allowed:

a {
  background: -webkit-linear-gradient(red, blue), -webkit-linear-gradient(black, white);
  background: linear-gradient(red, blue), linear-gradient(black, white);
}

But this will be more involved and will require using the value parser. As such, I think we're okay to introduce the option in its current form and this more complex use case can be addressed later down the line only if there's a real-world need for it.

@jeddy3 It is indeed a bit more complex to test 😅
I could look into it once this PR is merged (we know this one works, I'd rather land it right now before messing with it 😆 )

@jeddy3 I think my PR is ready to be reviewed ;)

Looking good.

Thanks, but let's wait until someone requests the feature before we add it.

[MightyCreak]

We'll need update tests to reflect this.

@jeddy3 it's fixed and the tests are updated as well (I needed to edit an older test in order to correspond with the new error message, see a52e9e8)

[jeddy3]

Thank you, LGTM!

Thanks, LGTM 👍🏼

I've left a trivial suggestion but I think this is ready to merge!
