deno: --help should get either wrapped to 80 symbols or terminal width

[yarikoptic]

ATM it would look like

with me having

❯ stty size
56 86

on my terminal. And require a very wide terminal to actually show it unwrapped/without distortions

so overall seems like if (Default ...) is printed under the option descrioption, it would already be mostly ok

The max width is currently set, pretty firmly, in the CLI library. c4spar/deno-cliffy#761 implements flexible resizing of the description and type columns, based on the terminal width.

At 72 characters, it's:
