### Description
The following jobs started failing when go 1.20.6 was released:
- `go-test-api-1-19`
- `go-test-api-1-20`
- `compatibility-integration-tests`
- `upgrade-integration-tests`

`compatibility-integration-tests` and `compatibility-integration-tests`
to this testcontainers issue:
testcontainers/testcontainers-go#1359. This
issue calls for testcontainers to release a new version when one of
their dependencies is fixed. When that is done, we will unpin the go
versions in `compatibility-integration-tests` and
`compatibility-integration-tests`.

### Testing & Reproduction steps

See these jobs broken in CI and then see them work with this PR.
