Load multiple env files

[QuangHD-GearInc]

What is the problem?

I saw in the document, we can pass all the environments as comma-separated strings. For example:

blitz dev --env staging,production

But It didn't work with my nextjs 13 project. I only can run with 1 environment.
How can I run with multiple env files?

Run blitz -v and paste the output here:

@QuangHD-GearInc Thanks for the issue!

we can currently set the APP_ENV to a singular environment which will in-turn load the env files of the following pattern

`.env.${APP_ENV}.local`,
`.env.${APP_ENV}`,
`.env.local` //if `APP_ENV` is not a test 
`.env`,

can you paste the link to docs mentioning that we can pass environments as comma-separated strings, so that it can be fixed?
