Add ignoreProperties option to length-zero-no-unit

[Mouvedia]

use case

flex used to require an unit for the flex-basis value.

unitless zero will either be interpreted as one of the flexibilities, or is a syntax error

browsers affected: IE10–11

What solution would you like to see?

{
  "length-zero-no-unit": [true,  {
    "ignoreProperties": ["flex"]
  }]
}

@Mouvedia Thanks for the report. But, flex is specially handled already. See #5315. Is a new option still necessary?

stylelint/lib/rules/length-zero-no-unit/index.mjs

Line 136 in 3edaa03

if (isFlex(prop)) return;

Indeed.

Is a new option still necessary?

No it's not.

see #4831 for the reason
