fix: add user info to context for set metadata in actions (#10426)

# Which Problems Are Solved

User information in the context is necessary through the addition of the
resource based API endpoints for user metadata, for the permission
check.

# How the Problems Are Solved

Add user information to the action execution to add metadata to users.

# Additional Changes

None

# Additional Context

Needs to be added to v4 releases, to provide the functionality to add
metadata through actions v1 and actions v2 functions.
