SectorsFile.php: remove unintentional indentation (#1787)

As a result of the indentation for the switch from engine pages to Page
classes in 5825816, literal multi-line strings were accidentally
prepended with tabs. This extra whitespace broke importing the SMR file
in MGU.

We remove the prepended whitespace here by avoiding literal multiline
strings.
