Update vector_properties.rst

[stra2da]

Proposed changes are for consistency with the GUI and between the paragraphs describing the renderer.
Please note I didn't change the index

I agree with moving the "renderer" word from :guilabel: directives, but I wouls not remove them from titles.

Agreed. And I would add it to those missing it.
I think it gives more meaning to the title.

[stra2da]

Ok, I will move the "renderer" word from :guilabel: directives and add it to the titles missing it
(Inverted polygon, Heatmap).
I would change also the title "Rule-based rendering" into "Rule-base Renderer".
Ok?
I'll have to do another pull request for theese changes, not yet using git...

[DelazJ]

OK for your suggestions!
No need to do a new pull request; you can do as many changes as you wish using the online github infrastructure: click the Files changed tab above and then the pencil next to the file name and you can edit the file.
Same procedure is to edit https://github.com/stra2da/QGIS-Documentation/blob/patch-3/source/docs/user_manual/working_with_vector/vector_properties.rst (the vector_properties file from your branch)

[DelazJ]

I would change also the title "Rule-based rendering" into "Rule-base Renderer".

euh... rule-base or rule-based?

[stra2da]

oh no!
Rule-based, I would change "rendering" with "renderer", according with the others titles :)

Thanks @stra2da
