What type of PR is this?
Enhancement

What does this PR do? Why is it needed?
Currently, when we specify a log file for the beacon chain node and if the log file parent directories are not present then we don't create the directory and error out. This PR adds support to create the parent directories if not present.

Which issues(s) does this PR fix?

Fixes (#12496)
