To support historical versions' documentation

[2BAB]

Is your feature request related to a problem? Please describe.
Not a runtime feature request but document, I was looking into an old version project which uses Koin 3.2 and want to check some apis availability. Therefore I found that Koin does not have the historical versions' documentation.

Describe the solution you'd like
We can have something like this: https://docusaurus.io/ (A document static site framework, from Facebook)

Describe alternatives you've considered
Go to the github, switch to the specific tag and check doc source.
