Sean Teo 6e4e414771 chore(deps)!: Migrate to Valkey from Redis (#775) 
<!--
 Before you open the request please review the following guidelines and tips to help it be more easily integrated:

 - Describe the scope of your change - i.e. what the change does.
 - Describe any known limitations with your change.
 - Please run any tests or examples that can exercise your modified code.

 Thank you for contributing! We will try to review, test and integrate the change as soon as we can.
 -->

### Description of the change

Migrates from Redis to Valkey.

### Benefits

The Redis License is changing from BSD-3-Clause to RSALv2 and SSPLv1 which are not open source under the OSI definition. We should consider open-source alternatives as a default replacement for Redis.

### Possible drawbacks

Large scale change, potentially breaking.

### Applicable issues

https://github.com/go-gitea/gitea/issues/32056

### ⚠ BREAKING

Major version change, redis provider changed to valkey.

### Checklist

<!-- [Place an '[X]' (no spaces) in all applicable fields. Please remove unrelated fields.] -->

- [X] Parameters are documented in the `values.yaml` and added to the `README.md` using [readme-generator-for-helm](https://github.com/bitnami-labs/readme-generator-for-helm)
- [X] Breaking changes are documented in the `README.md`
- [X] Helm templating unittests are added (required when changing anything in `templates` folder)
