[#301] Add Michał Szałowski to SSH access list for environment manage…

…ment

This commit updates the user_data.sh script within the Terraform modules
for govtool-EC2 instances. It adds Michał Szałowski to the list of users
authorized for SSH access, thereby expanding the secure access
management system to include a team leader. This change is a step
towards fulfilling the secure credential sharing acceptance criterion by
ensuring new team members like Michał have the necessary access to
sensitive environments.
