Added scrollbars to the codeblocks

[MMuschner]

By adding scrollbars to the codeblocks, both verticaly and
horizontialy, the checks catalog should be more comfortable to use.

fix #365

Thanks for the contribution, really appreciated!

Just a question, why the max-height?

[MMuschner]

I experimented a bit and thought it would fit

It looks nice! Maybe it would be better to create a new class with these styles, to avoid styling all the pre tags. Maybe by now we don't have others, but it would help to reduce issues in the future.

By the way, thank you for adding the gif!!!

@arbulu89 I actually agree but it's inside the .ha-check-remediation block, so the rule applies only in that context. Do you prefer to have a whole new class for that?

No, it is fine this way. Thanks @dottorblaster
