Add text_wrap environment variable

[codingjoe]

@codingjoe Yes, to do text-wrapping you'd need to pass word_wrap=True to the Syntax constructor: https://rich.readthedocs.io/en/latest/reference/syntax.html#module-rich.syntax

Can this just be the default, or does it need a command-line flag?

Hm... maybe default based on the very common CI environment variable?

@codingjoe I don't think this should be tied to CI; text-wrapping can be useful in the console too.

Good point, actually, let's always wrap :)

@codingjoe Great; that's just a one-line change, I believe. I've opened a PR.
