New Release with updated Runner version

[MGreif]

Hola,

the latest released docker image contains the Runner version 2.273.5. The latest official github-runner version is 2.311.0.

This causes some github actions to use older versions, that in turn use deprecated modules.

E.g:

FYI: node12 is deprecated for a long time and latest versions of NextJS need to be build with node18+.

Cloning the repo and building it myself fixed the issue, tho it would be nice to just pull an updated version :)

I think scheduling an release workflow once a month could solve this issue 🤷‍♂️

Regards,
Mika
