This test fails due to a bad interaction when `FFlagLuauStoreCSTData` is
enabled, whilst `FFlagLexerFixInterpStringStart` is disabled.
The OSS test suite, when run with `--fflags=true`, enables all
flags starting with a `Luau` prefix, but does not enable any other flag.

To resolve this, we explicitly enable both fflags for the failing
interpolated string test cases. As a consequence, we technically lose
the check that these tests pass when all flags are disabled.
