Recognise a semicolon-terminated example heredoc as documented usage

InternalComponentsTest strips a showcase example's <<<'BLADE' heredoc
before checking that a package view only ever refers to its own
components through the livewire-material:: namespace, since an
example heredoc documents an application's own (unprefixed) usage.
The check only recognised an array's BLADE, terminator; the Layout
section's three dedicated pages (plan step 38) assign their one
example to $code with BLADE; instead, which the check now strips too.
