Zig has textobjects: helix's query, ported to the zig grammar pardes builds

pardes builds maxxnino/tree-sitter-zig, whose node names are not those of
the grammar helix's query targets, so the query is ported by hand
(vendor/queries/zig, its MPL header saying it is modified and how): a
function is a Decl holding an FnProto and a Block with pub beside it,
struct/enum/union one ContainerDecl, parameters and arguments ParamDeclList
and FnCallArguments, and comments come in three kinds. That grammar's
comments take their line's newline, and a node ending in a newline is now
taken without it, as helix's grammars have it. The replay test gains fifteen
Zig cases from the installed hx; none walks call arguments, which the
reference helix counts as parameters and 25.07.1's query does not.
