Add dbt-synapse to 1.7.latest

[colin-rogers-dbt]

Now that dbt-synapse supports 1.7 we want to begin including it in bundles. This ticket only covers adding the adapter to requirements and does not include any further validation/testing

Acceptance Criteria:
The version has been added. If it fails for any reason, stop the ticket and discuss in the channel.

Moving to blocked. Adding dbt-synapse to the bundle appears to require py311 to build.

This might have been a false alarm, looking further into the failure in the background of other tasks.

So the tests are passing for 1.0 through 1.7. They're failing on main/1.8. I don't know if it's happening because it's 1.8 or because it's installing from GitHub. The dependency called out in the error is hatchling, which is only used in 1.8. But it could arise from other combinations of dependencies.
