Fix folder references for post start hooks on using custom model templates

[theblinkingusb]

Not a helm pro here by any means but I believe the ollama.modelsMountPath is missing a condition to check when the mountPath has been changed thereby affecting postStart hooks in the ollama.create functionality.

ollama-helm/templates/deployment.yaml

Line 183 in c71a862

cat <<EOF > {{ include "ollama.modelsMountPath" $ }}/{{ .name }}

evaluates to a /root/ path. So then this PR would match the behavior to

ollama-helm/templates/deployment.yaml

Line 123 in c71a862

mountPath: {{ .Values.ollama.mountPath | default "/root/.ollama" }}

Summary of changes:
Update _helpers.tpl file to respect custom mountPaths when using ollama.create templates/modelfiles.
Update deployment.yaml to retrieve same variable value
Update Chart.yaml per PR requirements.

Please let me know if I need to change anything here - I was able to run this locally against my desired chart values (with custom templates + non root) - thanks

Checklist:

• I updated the artifacthub.io/changes annotation in Chart.yml according to the documentation
• Optional: I updated in README.md the Helm Values

For clarification - this bug appeared when using the ollama.create + template feature in the chart while also changing off root path - that's when I noticed the postStart hook failing due to pointing at the root dir.
