Wrong default value for table-index-cache-max-entries

Table-index-cache-max-entries says dafeult value is 1000, but the code default value is 100.

##### Relevant URLs
- https://docs.influxdata.com/influxdb3/enterprise/reference/config-options/#table-index-cache-max-entries
- https://github.com/influxdata/influxdb/blob/main/influxdb3/src/commands/serve.rs#L359

Open the linked documentation page and compare its table-index-cache-max-entries default with the value in influxdb3/src/commands/serve.rs around line 359. Update the documentation so the stated default matches the code, then verify the option page shows the corrected value.
