Github identifier format in docs/source/conf.py

[NGC2023]

Hi,
I'm currently working on packaging opt_einsum v3.3.0 for Debian. While reviewing the code, I noticed an issue with the Github identifier format in docs/source/conf.py. I've prepared a patch to address this problem.

@NGC2023 Thank you for the report, fortunately we have moved to mkdocs which has removed these files. We are currently preparing for another release.
