Make show source code feature be less visually intrusive (discreet)

[ssbarnea]

Is your feature request related to a problem? Please describe.

While "show source" is an extremely useful feature, Is just that I wish it would be less-in-your-face. If we could make it more subtle, like as simple [src] dimmed text after the member/method name, something that would not take any horizontal space on the page it would be much better.

Look at screenshot below an count how much vertical space is consumed by "show source code".

Describe the solution you'd like

Find a way to display the "source" button in a way that does not take more vertical space.

Describe alternatives you've considered

Additional context

Initially reported on #35 (comment)

Any suggestion on how this should be showed is welcomed. Probably having an icon is also an less intrusive way but I still think that it should be somewhere near the title of the element for which we will display the source and not after its documentation.

The source was initially displayed right after the name, but then the line numbers of the source were showing up in the search results. I think this search issue has been fixed since then, so we could move it back right after the name. I guess a collapsible element with a relative/float position would do the trick 🤔 I'm not good at CSS/webUIs though, so any help is welcome!

I managed to accomplish this by adding this to my mkdocs.yml

plugins:
  - mkdocstrings:
      handlers:
          python:
            options:
              show_source: false

I got it from mkdocstrings documentation.
