[vim/vim] Fix cssBoxProp not matching correctly (Issue #18715)

[Neil Lambert]

nlambert created an issue (vim/vim#18715)

Steps to reproduce

Create or edit a CSS file.

Paste the following:

div {
  margin-block: 1px;
  margin-block-start: 1px;
  margin-block-end: 1px;
}

See margin-block not highlighted while the two others are.

Expected behaviour

All three properties should be properly highlighted.

The current regex optionally matches the 2 last segments together.

It does not make the last segment dependent on the second.

The rule should be:

syn match cssBoxProp contained "\<\(margin\|padding\)\(-\(inline\|block\)\(-\(start\|end\)\)\=\)\=\>"
