Suggestion: Issue templates

[joshkel]

The Knex site's GitHub link points to the documentation repo rather than the main project repo; I'm more familiar with OSS project websites linking to their project repos.

Possibly because of this, several of the open issues under https://github.com/knex/documentation appear to be about Knex itself, rather than issues or suggestions for the documentation website.

Using GitHub's issue templates feature could help guide users to the appropriate place to file their issues.

See https://github.com/joshkel/knex-documentation/issues/new/choose for an example of what this looks like.

Just a suggestion - feel free to edit or ignore.

The website repo has been moved inside the https://github.com/knex/knex repo. Please open a PR there instead: (the website will be under the docs folder)
