🪲 Remove valid assignment uses from ask command errors

[boryanagoncharenko]

Fixes #3274
In levels 1-6 the ask and assign commands sometimes overlap and sometimes return an error incorrectly. With this PR, some correct usages are removed from the common error scenarios. Specifically:

• in levels 2-3 assignments can have variable names starting with ask, e.g. asking is 5, ask_output is test
• in levels 4-6 assignments can start with the word ask, e.g. var is asking you a question

However, the incorrect uses of ask should still return an error:

• in levels 2-3 ask what is it? should return a wrong level exception
• in levels 4-6 var is ask what is it? should return a missing quotes exception

How to test

# in level 2
ask missing var
# this should return an error

asks is Felienne
# this should defined a variable ‘asks’

# in level 3, language NL
vraaga is vind je honden aardig, doe jij teveel gamen, je ging op pad
print vraaga at random
# this should not yield an error

# in level 4 and 6
var is asking me a question?
print var
# this should not yield an error

Awesome, this was such a longstanding issue!
