fix: handle network error on SETINFO (#3295) (CVE-2025-29923)

* fix: handle network error on SETINFO

This fix addresses potential out of order responses as described in `CVE-2025-29923`

* fix: deprecate DisableIndentity and introduce DisableIdentity

Both options will work before V10. In v10 DisableIndentity will be dropped. The preferred flag to use is `DisableIdentity`.

#### Disabling Identity Verification
When connection identity verification is not required or needs to be explicitly disabled, a `DisableIndentity` configuration option exists. In V10 of this library, `DisableIndentity` will become `DisableIdentity` in order to fix the associated typo.
When connection identity verification is not required or needs to be explicitly disabled, a `DisableIdentity` configuration option exists.
Initially there was a typo and the option was named `DisableIndentity` instead of `DisableIdentity`. The misspelled option is marked as Deprecated and will be removed in V10 of this library.
Although both options will work at the moment, the correct option is `DisableIdentity`. The deprecated option will be removed in V10 of this library, so please use the correct option name to avoid any issues.
To disable verification, set the `DisableIndentity` option to `true` in the Redis client options:
To disable verification, set the `DisableIdentity` option to `true` in the Redis client options:
```go
rdb := redis.NewClient(&redis.Options{
Addr: "localhost:6379",
Password: "",
DB: 0,
DisableIndentity: true, // Disable set-info on connect
DisableIdentity: true, // Disable set-info on connect
})
