[Bug] New g.parser manual page has an unexpected title

[echoix]

Describe the bug

g.parser has a weird title in the new docs.

To reproduce

I recently found out that the new manual pages are published online (yay! they are so nice!). I was looking at g.tempfile, then I wanted to see other g.* commands with a similar name. Since there isn't a sidebar with the other function names, I clicked on the keyword/tag at the top, and got the following:

I found the tool called Provides full parser support for GRASS scripts unexpected, so I checked it out. It is finally g.parser, but it isn't obvious.

Expected behavior

The tool is called g.parser and not Provides full parser support for GRASS scripts.

This is a larger issue with the conversion to markdown from html. The pages in questions include an extra first level markdown header #. MkDocs gets the first level header from the yaml metadata name. To correct this we need to updated the impacted files. Which can be found by filtering the files with the regex ^# and limiting the search to include only markdown files ( thanks @echoix).

Here is an example from g.gui.example.md.

@wenzeslaus when working on PR https://github.com/OSGeo/grass/pull/5169/files do you remember if there was a reason for setting the title using # instead of setting the title in the page metadata?
