Docs do not currently have a license file

[RCheesley]

I noticed when writing up some documentation, that we haven't currently got a license file associated with our documentation repos. We should probably decide what license we should be sharing under.

Perhaps we could consider https://creativecommons.org/licenses/by-sa/4.0?

[CBID2]

I've seen most open source projects use the MIT License @RCheesley. Maybe we could go with that one?

It's something to consider @CBID2 however given Mautic is licensed under the copyleft GPLv3, using MIT for the documentation is a less restrictive license meaning that the docs can be published, distributed, sub-licensed and sold, whereas CC-BY-SA would mean that it had to be shared under the same terms.

Perhaps this could be a discussion that the education team could facilitate @favour-chibueze ?
