* chore: add /v2 to import module path
go mod requires semantic versioning with versions greater than 1.x
This was a mechanical update by running:
```
go install github.com/marwan-at-work/mod/cmd/mod@latest
mod upgrade
```
Migrate generated files to import /v2
* Fix gen
* feat: Add AWS instance identity authentication
This allows zero-trust authentication for all AWS instances.
Prior to this, AWS instances could be used by passing `CODER_TOKEN`
as an environment variable to the startup script. AWS explicitly
states that secrets should not be passed in startup scripts because
it's user-readable.
* Fix sha256 verbosity
* Fix HTTP client being exposed on auth
