Adrien Grand d0104c22a5 Reduce the default number of cached queries. (#26949)
Memory usage of queries can't be properly accounted, which can be an issue when
large queries are cached since the actual memory usage will be much higher than
what the cache thinks. This problem is very hard if not impossible to fix so as
a workaround I would like to decrease the maximum number of cached queries so
that this problem is less likely to cause trouble in practice.

For the record, this problem is more likely to occur in envirenments that have
small shards or don't give much memory to the JVM.

Closes #26938
