fix: handle line breaks

[r-o-b-o-t-o]

What does it do?

Transforms \n, \r\n and \r into <br /> tags in <Text />

Why is it needed?

Fixes #37

How to test it?

• Create rich text blocks with line returns in them (⇧+⏎ in the rich text editor)
• Render them with <BlocksRenderer />
• Make sure the newline characters are replaced by <br /> tags

Looks good, could you just add a unit test too?

And sorry I wasn't aware of this PR, it's been a while so if you don't want to get back to it we can make another PR internally
