Horizontal scrolling in rendered code blocks

Currently `docs-ts` [uses prettier to format](https://github.com/gcanti/docs-ts/blob/3a98908f6fd9aa2d47fe23df57bf9422b7f346d1/src/Markdown.ts#L568) markdown before writing out the docs.

The used options are:

```ts
const prettierOptions: prettier.Options = {
parser: 'markdown',
semi: false,
singleQuote: true,
printWidth: 120
}
```

The code blocks in Jekyll seem to work without horizontal scrolling only if lines don't exceed a 80 characters limit.

*Is this intended behavior?*

If not, I'd suggest one of those options:

- Configure Jekyll to use 120 characters as limit (don't know if this is possible)
- Configure Prettier to use 80 character limit

Or, and this Is what I would suggest:

- Don't format at all inside `docs-ts` and encourage the user to use [prettier-plugin-jsdoc](https://github.com/hosseinmd/prettier-plugin-jsdoc#readme). This is a much better editing experience. You have more control about the format, plus in the end the actual source file has the same formatting as the docs.

What do you think?

Start in src/Markdown.ts at the referenced Prettier formatting call and review the shown markdown options, especially printWidth. Compare the generated Jekyll code blocks with the reported 80-character scrolling behavior. The issue does not select an implementation or define a final acceptance condition, so the intended formatting policy must be resolved before work can be considered done.
