bug: tags missing from images in docker hub

[DouglasWillis1]

Describe the issue

Latest chart uses fluent bit image tag v3.0.4 but that image tag is not on docker hub.

To Reproduce

try and pull image from docker hub.

Step 2/2 : FROM kubesphere/fluent-bit:${IMAGE_VERSION}
12:19:23  manifest for kubesphere/fluent-bit:v3.0.4 not found: manifest unknown: manifest unknown

Expected behavior

Image is available to support the chart

Your Environment

- Fluent Operator version: 2.8.0
- Container Runtime: containerd
- Operating system: Linux
- Kernel version:

How did you install fluent operator?

Helm

Additional context

No response

[DouglasWillis1]

Additionally noticed that the artefact name for the latest release in git has had a version added to the filename.

Name for the v2.8.0 release
fluent-operator-2.8.0.tgz

Name for all other release
fluent-operator.tgz

This makes the Documentation for installing incorrect.

EG:
From the README.md file.

helm install fluent-operator --create-namespace -n fluent https://github.com/fluent/fluent-operator/releases/download/< version >/fluent-operator.tgz
