fix parisng of tasks env vars in go

[akosyakov]

Description

Our gitpod protocol schema allows any as a type for env vars of tasks. This PR adjusts typings to respect it in the code.
We considered also to make the scheme more strict, but it will be a breaking change, and there is no apparent downside of any value given that clients expect that the value be serialized/deserialized as JSON.

How to test

• Start a workspace on the repo which is using not string env var for tasks: https://akosyakov-gitpod-yml-tasks-not-5699.staging.gitpod-dev.com/#https://github.com/akosyakov/sir-lancebot/blob/eca8bcebf7c47de7fa661009df583fe79b95334e/.gitpod.yml#L5
• Check that the task terminal is running and env var is set: printenv PIP_USER should be false.

Release Notes

Fix parsing of tasks' env vars.
