fix: container environment variables

[sellooh]

Container variables are being ignored and top level environment can't be set when using containers

Since this condition doesn't allow to specify top level environment variables, there is no workaround atm: https://github.com/sst/ion/blob/64a591a62287089adbf0f09636dd9f9112112814/platform/src/components/aws/service.ts#L232

This PR adds container env variables to the task definition

closes https://github.com/sst/ion/issues/1204

What's holding this pr back? Would love to get that fix.

Had conflicts with my PR and just fixed them - would also like to get this fixed, I'm using a patched version of the component for now but would love to just use SST's
