🪲 Add support for numbers in return statements

[boryanagoncharenko]

Fixes #5170
With this PR, return statements try to convert their output to integers and floats and output strings if the number conversion fails. This change is required because the output of a function cannot be used in an arithmetic operation.

How to test
Navigate to level 14 and run the following program. Ensure that it completes without an error:

define round with x
    return x

r = call round with 1
print r + 1

Thanks for looking into it!

Yes, the program will still fail when you try it at https://www.hedycode.com and this is normal. The reason is that the code in this pull request has been merged to the main branch but has not been deployed to https://www.hedycode.com yet. If you want to run this new version, you would have to run Hedy locally (we have great docs). Otherwise, you could wait a few days and the fix will become available at https://www.hedycode.com.
