fix(compiler-solid): Props replacement not working with multiline starttags

[NathanHuisman]

Description

Props replacement wasn't working because the lookbehind only included the symbol '.', which doesn't match newlines.

According to the XML spec, newlines can be included in the spacing in a starttag.

This was a very quick fix, so I figured I did not need to create an issue

Input:

<svg
  width="35"
  height="44"
  viewBox="0 0 35 44"
  fill="currentColor"
  xmlns="http://www.w3.org/2000/svg"
  role="presentation"
>
<!-- (left out, irrelevant) -->
</svg>

Output before fix:

export default (props = {}) => <svg
  width="35"
  height="44"
  viewBox="0 0 35 44"
  fill="currentColor"
  xmlns="http://www.w3.org/2000/svg"
  role="presentation"
>
{/* (left out, irrelevant) */}
</svg>

Output after fix:

export default (props = {}) => <svg
  width="35"
  height="44"
  viewBox="0 0 35 44"
  fill="currentColor"
  xmlns="http://www.w3.org/2000/svg"
  role="presentation"
{...props}>
{/* (left out, irrelevant) */}
</svg>
