Typo in: TestRemoveNewLineSuffix_EndingWithoutNewline (page 272, incosistent with page 273)

Hello,

I noticed a likely typo in Chapter 11 (Testing), page 272.

The test: TestRemoveNewLineSuffix_EndingWithoutNewline

uses: got := removeNewLineSuffixes("a\n")

However, this duplicates the “EndingWithNewLine” (page 271) case and does not test the “without newline” scenario.

On page 273, the table-driven version correctly uses: input: "a"

So I believe the page 272 test should also use "a" instead of "a\n".

Thanks for the great book!
