🪲 Revise runtime errors to include actual values

[boryanagoncharenko]

Fixes #5005
Value errors display the actual value that is causing the error instead of the variable name holding this value.

Run Hedy locally and check whether the following programs produce correct error messages. Ensure that you supply text values to all ask commands and that the errors contain the actual value you supplied.
