Remove export and quotes from generated .okta.env

Today I realized that there's really no reason for .okta.env to have export or use quotes around values. If we remove export and the quotes from the values, running source .okta.env will still set the environment variables.

I'm not sure if this will work on Windows. However, if it does, I think we should switch to it and update old blog posts. With the CLI include, it should be easy.

One of the nice things about moving to a syntax recognized by dotenv is you can copy/paste into your IDE for environment variables and you can also rename it to .env and it'll set the variables for Docker Compose.

I tested this on Windows today. Using FOO=bar doesn't work on Windows like it does on macOS and Linux. 😕
