[qBittorrent] Bump bjw-s common chart version to 3.7.x

[vincentkelleher]

Hi 👋

I noticed that the BJW-S common Helm chart dependency was a bit out-of-date while trying to deploy qBittorrent with an NFS mount point described as an existing PersistentVolumeClaim (useful to add some NFS mount options).

This pull request proposes an update of this chart dependency with a few changes as it's a major version bump such as:

• a new values.yaml organization
• a different way of defining the dependency's version to allow for minor and patch updates to be pulled automatically during updates
• the deletion of the NOTES.txt file as the new BJW-S common chart doesn't seem to support notes generation

I've tested everything with a basic values.yaml file I wrote for my home lab and with the helm template command, everything seems to work fine ✅

@vincentkelleher Hey! Thanks for opening this. I'll do some testing and merge this PR soon. I've been slightly hesitant to update all of these charts since v2 and v3 have major breaking changes, and ever since bjw-s released his app-template chart, I've been using that one in my personal infra anyways. That being said, I'm not against updating. I just feel bad making everyone redo their values 😅
