Upgrade CPU capacity of bridge
The snowflake bridge is currently using most of its 4 CPUs. Most of the use is by snowflake-server. This was noticed by @meskio at #40060 (comment 2767868).

We should probably profile snowflake-server to find the hotspots to reduce its CPU usage (#40086), but for now we can redeploy on hardware with more CPUs. We're still doing okay with memory.
We are currently using
- 8 GiB / 4 CPU cores (40.75 credits)
And our options for upgrading are
- 12 GiB / 6 CPU cores (60.75 credits)
- 16 GiB / 8 CPU cores (80.75 credits)
I would tend to push it to the max, seeing how user growth is going.
A previous bridge upgrade issue was #40051 (closed).
