Fix releasenotes (#1543)

* fix: correct YAML indentation in update-releasenotes workflow

The Python heredoc content was at column 1, which broke out of the
YAML block scalar for the 'run' key. Indented the heredoc body to
align with the run block so YAML parses it correctly. The block
scalar automatically strips the common indentation, so Python
receives the code without extra leading spaces.

* fix: export shell variables for python subprocess in release notes workflow

FILE and VERSION_HEADER were plain shell variables, invisible to the
python3 heredoc subprocess via os.environ. Adding 'export' fixes the
KeyError.
