Stitches example: Greedy regexp pattern potentially breaks markup

[nimajneb]

Hi!

The stitches example uses a Regexp pattern to replace the style tag in SSR with the actual server side rendered styles.

However, the pattern used to do this is too greedy. I just had an example in which I have multiple additional style tags also in the the whole document body, which got all replaced until the last closing style tag.

By replacing .* with .*? I believe this issue should be fixed.

Additionally, also matching newlines by using the /s flag might avoid another issue in case the SSR stylesheet contains newlines, though I am unsure how much of an edge case this is.

I just quickly created a PR in case you want to address the issue directly. Cheers!
