grid-template-areas in multiline format?

[vofronte]

Hello!)

Is it possible to configure linting for the grid-template-areas property in this format?

.wrapper
  display grid
  grid-template-columns 1fr 1fr
  grid-template-areas
    "header header"\
    "navigation content"\
    "footer footer"

Currently it's only allowed to write it in one line. But in this format it's much more convenient to read.

Currently this plugin does not have rules to check that format.
If you want to add a new rule, please send a PR 😄
