Install the exact version instead of range

`^version` means install any version that is compatible with the range.
This means npm can even install tree-sitter-javascript version 0.15
since in semver 0.15 should be compatible with 0.19. tree-sitter seems
to have broken semver. 0.15 is not compatible with 0.19
