CMakePackageConfigHelpers: Fix note about version files supporting ranges
In !5613 (merged) the documentation for
write_basic_package_version_file
documented the support of version
ranges by the generated version files, however the note wrongly
specifies a COMPATIBILITY_MODE
argument, instead of COMPATIBILITY
.
This already resulted in a misunderstanding here: https://github.com/jeremy-rifkin/libassert/pull/18#discussion_r869645140
Backport: release
Topic-rename: doc-package-compatibility-mode
