update dbt-synapse requirements for 1.7 and 1.8

[dataders]

there's now a

• dbt-synapse 1.7.4 (PyPI)
• dbt-synapse 1.8.0rc3` (PyPI)

I see that both the 1.7.latest and 1.8.pre bundle requirements have compatibility pins, so in theory these releases should be included, but perhaps we should update to make these versions the minimum? Not sure what's needed here
