fix(syntaxes): add back block syntaxes to injection for entire TS file

We rely on the `injectionSelector` to prevent matching our grammars in
contexts which they should not apply. The `injectionSelector` only applies
when the grammar is injected to the file via `injectTo`. Otherwise, the
grammer is applied directly when it is included in the `patterns` array
of another match.

fixes #2062
