config: Lower default [database].MAX_OPEN_CONNS (#10821)

Browse source 
Resolves https://codeberg.org/forgejo/forgejo/issues/10584

Codeberg mostly uses about 30 connections with rare peaks, so I think it's safe to assume that this value is reasonable even for large Forgejo deployments, and only needs to be adjusted for very busy instances. In practice, the open connections likely remain lower due to the connection lifetime and maximum idle connections (which could maybe also be tuned later). A value of 30 would technically allow 3 full-loaded Forgejo instances to operate on one PostgreSQL instance (30 * 3 = 90 < 97) without conflicting.
