C1_W3_Assignment typos

[Thomas_A_W]

I noticed 2 minor typos in the assignment.

In the initial section, the word “correspond” is misspelled “corresponde”.

In the start of the section for exercise 5, the variable name “n_components” is misspelled “n_componentns”.

Thanks @Thomas_A_W, for bring this to our attention. These will be fixed soon.
