unable to use mysql@3* as peer dependency

[Johan Eliasson]

This PR seems to be using an incorrect syntax for adding support for multiple major versions of mysql2.

Correct syntax:

    "mysql2": "^2.3.3 || ^3.0.0",

For now I can get around this issue by using npm install --save-dev kysely-codegen --force.

Should be fixed in kysely-codegen@0.10.1!
