Let's merge this PR and give CI a try to rebuild docker images. In case if build fails I will revert it

@xiaoxiang781216 could we hold on the further merges until https://github.com/apache/nuttx/actions/runs/6234041079/job/16920715873 is finished? I want to get a feedback from the current change

[pkarashchenko]

Seems like the error with C++ still persists

@pkarashchenko Seems the docker image is not up to date, still use the gcc 13 that merged yesterday.

[xiaoxiang781216]

I create a patch(#10717) try to update the docker image again. Let's see what's happen.
