fix(ci): add cwd prefix to bake-file reference (#511)

The release GitHub action is broken now because of a breaking change in
`docker/bake-action` GitHub action after upgrading from v5 to v6.

## Changes

- Added `cwd://` prefix to the bake-file reference in the GitHub action.
- Added terraform 1.11.4 to build matrix
