Change timeout length of pupeteer

[s-thomas99]

I use custom css for my grafana which issues in some errors

rendering timeout set to 5seconds

podman container with v4.0.13

I want to reduce that timeout:
{"err":"TimeoutError: Navigation timeout of 60000 ms exceeded\n at new Deferred (/home/nonroot/node_modules/puppeteer-core/lib/cjs/puppeteer/util/Deferred.js:59:34)\n

Environment:

• Grafana Image Renderer version: 4.0.13
• Grafana version: 11.4.6
• Installed plugin or remote renderer service: own podman container
• OS Grafana Image Renderer is installed on: RHEL 9
• User OS & Browser: Admin User / Edge Browser

This might be the root cause which causes the timeout:
{"level":"error","message":"Browser console error","msg":"Refused to apply style from 'http://grafana:3000/public/img/theme.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled."

I'm having a related issue. Really just wnat the ability to control the 60000ms timeout via an env variable or something. Created an issue for it here #785 before I saw yours. Let me know if this matches your experienced.
