Add documentation and examples for the trigonometric filter operators (#6131)

Browse Source 
* Added missing trigonometrics filter operators

This PR adds support to trigonometry operators, allowing to create spider graphs and other geometric shapes with filters.

* Adds the missing trigonometric filter operators

This PR adds support to the missing trigonometric filter operators (cos, sin, tan, acos, asin, atan, atan2), allowing to create spider graphs, [pie charts, donut charts, polar charts](https://ffoodd.github.io/chaarts/pie-charts.html) and other geometric shapes with filters, which was previously not possible without add-ons.

Example :

`[[2]cos[]] = -0.4161468365471424`

See also this radar chart made in wikitext by @saqimtiaz using the new trigonometric operators :

* Add documentation for the Trigonometric Operators 

Accompanies code changes #6127

* Fix formatting of atan2 Operator.tid

Removed two empty lines at the end of the tiddler

* Add examples for the trigonometric operators 

Accompanies code changes Jermolene#6127

* Fix version in the doc for trigonometric operators

This PR fix the content of the documentation tiddlers regarding trigonometric operators (#6131). 

<<.from-version "5.1.20">> was changed to <<.from-version "5.1.21">>

* Fix formatting of atan2 Operator.tid

Removed two empty lines at the end of the tiddler
