fix(webkeys): remove include private key from projection index (#8436)

# Which Problems Are Solved

When Web keys with a large RSA Bitsize were generated, the new web key
did not get projected.
Zitadel logs printed the following errors:

```
time="2024-08-15T09:18:47Z" level=debug msg="execution of statements failed" caller="/home/tim/Repositories/zitadel/zitadel/internal/eventstore/handler/v2/handler.go:518" error="statement failed: ID=CRDB-pKtsr Message=exec failed Parent=(ERROR: index row size 3400 exceeds btree version 4 maximum 2704 for index \"web_keys_web_key_state_idx\" (SQLSTATE 54000))" lastProcessedIndex=-1 projection=projections.web_keys
```


# How the Problems Are Solved

Remove the the `WithInclude` option with the Private key from the
`web_keys` projection index and bump the projection version.
