Update image version to latest #10407 (#10408)

During the installation of otlp in recent days, it was found that the
installed version is somewhat outdated, which is not conducive to users
trying out the latest features. It's also unnecessary to modify the
installation yaml file every time a new version is released. Would it be
more appropriate to change it to "latest"?
