fix(css_formatter): don't indent CSS selector when leading comments before

[fireairforce]

Summary

closes: #4326

I add special judge for that case:

.a {
  /* hi */
  a,
  /* me */
 div {
   color: red;
  }
}

If i get a CSS_Type_Selector like: /* hi */\n a,\n div(you can refer this from above case), i will not add an ident for this to avoid this case, the previous logic at biome_css_formatter will add an ident for this case by default.

Test Plan

add test case like:

.with-comments {
  /* hello */
  a,
  /* world */
  button {
    color: blue;
  }
}

.without-comments {
  a,
  button {
    color: blue;
  }
}

my fix as follows:

.with-comments {
  /* hello */
  a,
  /* world */
-    button {
+  button{
    color: blue;
  }
}

You need to add something after the word "before" because, as is, it's incomplete
