Images aren't copied over anymore after upgrade to 4.1.0

[ahill187]

Describe the bug

After upgrading to Sphinx 4.1.0, our logo file is not being properly copied over. When we build our docs, the logo is missing. This was working perfectly fine before the upgrade.

We noticed that for our conf.py file with this line:

html_logo = './_static/img/sct_logo_blue.png'

the resulting path in the rendered version is:

'../_static/../imgs/sct_logo_blue.png'

Note how the folder name was changed from img to imgs?

How to Reproduce

$ git clone https://github.com/spinalcordtoolbox/spinalcordtoolbox
$ cd spinalcordtoolbox/documentation
$ pip install sphinx
$ pip install -r requirements.txt
$ make html
