Adding a way to display the license for the documentation at the bottom of the page

[mithro]

@mguthaus makes a good point in google/skywater-pdk#118 that we should display the license the documentation is at.

This should probably be a set of settings under html_theme_options;

• License Icon / Badge / Image URL
  • See "buttons" at https://creativecommons.org/about/downloads/
  • See https://shields.io/category/license
• Link to the license file on GitHub (IE https://github.com/google/skywater-pdk/blob/master/LICENSE or https://github.com/SymbiFlow/symbiflow-arch-defs/blob/master/COPYING)
• Trove or SPDX identifier value - https://spdx.org/licenses/

@daniellimws Any chance you could look at this?

[mithro]

It should be noted that the license for the documentation might not be the same as the license for the code repo.

[daniellimws]

@mithro I feel that a plain "License" string looks nicer than having the badge in the footer. What do you think?

[mithro]

I do think the non-badge format fits nicer /but/ I do like the badge has the actual license name in it.....

[daniellimws]

How about putting the license name in parenthesis, like License (ISC)? Or shall I change it to show the badge?

[mithro]

Putting the license name in parenthesis seems like an option.

[daniellimws]

We could query for the repository's license through the GitHub api, so the user would have less things to configure in conf.py, but that would require additional javascript.

@mithro What do you think, because of #4?

[mithro]

@daniellimws I would just make the user set it.
