docs: adding new logo to docs

[cwhite911]

I've added the new logo to the docs (See screenshot)

House keeping

We have two files grasslogo_vector.{eps|pdf} files in man directory that are used in utils/module_synopsis.sh and ps/ps.map/decorations.

Are these files still in use or can they be safely removed?

Note

This PR does not address updating the logo in the GUI. That issue is getting addressed in PR #5577

Check also the Sphinx-generated doc for Python API. That has a separate logo. I had to update that when updating the build. You should be able to check the result in the downloaded artifact if you are not building that locally.

Good catch, but they are referenced by these two, so why to remove?

I was looking at utils/module_synopsis.sh and that looked like dead code, so perhaps you can see (let AI figure out) what it is doing and delete that in separate PR with the corresponding logo file.

ps/ps.map/decorations is not deprecated or anything, so that needs to be updated or "thoughtfully removed".

Yes, please change also the logo in the python doc:

I've updated the eps and pdf versions of the logo, so they can work with PostScript.

@petrasovaa I'm going to address the logo for the python docs in another PR because I've updated them to MkDocs styling using the sphinx_material. So, this PR is good to go unless you have something else you want me to look at.

That's awesome and it looks great.
