Recognize help/version examples in TlDr pages and convert them to Help/Version tags with single value

[EmilyGraceSeville7cf]

Recognize just the following code samples:

- (Display|Show|Print)( a|the)? help:

`command (--help|-h|/?)`

and:

- (Display|Show|Print)( a|the)? version:

`command (--version|-v)`

They are written in regex-like manner.

I think this is how it can be done:

• I assume that page have some tag, like More information.
• Then I check whether I have help/version example.
• If I do, I remove it and add Help/Version tag before More information.
