Fix typos in test description of 'AmIRichAlready' tutorial

Corrected two typographical errors in the ## Testing section of the 'AmIRichAlready' contract tutorial:
1. Changed 'to the the AmIRichAlready' to 'for the AmIRichAlready' to clarify the sentence.
2. Fixed 'brake' to 'break' in 'Let's break down this test into parts' for proper grammar.
