chore: env manager patcher and service discovery namespace should work with bootstrap stack

[Lou1415926]

Previously, we have two fixes:

1. fix: ensure env manager role has permission to upload #3956 which patches the S3 permissions to the environment manager role if it's needed.
2. fix: preserve existing service discovery endpoint #3949 which preserves service discovery endpoint namespace from a previously deployed env stack.

Fix 1 performs an environment template version check to infer whether the necessary permissions are present. This version check fails to take into account the "bootstrap" version, which is present when the environment is only bootstrapped (by running env init and not having run env deploy)

Fix 2 grabs the old parameter from a deployed environment stack. It fails to take into consideration that, while an env stack that's on "bootstrap" version is not considered a "deployed environment" in Copilot, it is a deployed stack in CFN.

LGTM! I hadn't realized previously that we were using "boostrap" for version! 😄
