* Update generate_config.sh version checking for wider compatibility 

fix: replace `grep -oP` with `grep -oE` for broader compatibility

The `-P` option (Perl-compatible regex) is not supported in all versions of `grep`, particularly the default BSD `grep` on macOS. This change replaces `-P` with `-E` (extended regex), which is more widely available and ensures compatibility across different environments.

Tested on macOS and Linux.

* Update generate_config.sh to remove use of platform dependent grep

Replaced version checking using free-form text. Instead, uses Docker’s built-in templating instead of parsing free-form text. This gives cross-platform consistency without dependency on particular versions of grep.
