Docs: Investigate duplicate search results

[kirszenbaum]

In many cases, search shows two identical search results, for example:

This seems to affect the config.html page (not included in the TOC), which gets built from the ./src/Config.ts file.

The ./src/Config.ts file includes this line: https://github.com/handsontable/hyperformula/blob/master/src/Config.ts#L493

The @inheritDoc tag info: https://tsdoc.org/pages/tags/inheritdoc/

To do:

• [ ] Investigate the reason for "duplicate" search results
• [ ] Try to find a way to make them display separately (or remove duplicate entries from the docs entirely?)

Variable named dateFormats is a member of ConfigParams interface, Config class and defaultConfig public static variable. That's why it is shown thrice in the search results.

IMO the problem is that the search results don't show what class does a variable belong to.
