fix(solid-query): allow optional initialData in infiniteQueryOptions

[thribhuvan003]

🎯 Changes

Fixes #11286.

UndefinedInitialDataInfiniteOptions typed initialData as ?: undefined, so passing a value that might be undefined matched neither overload. The defined overload rejects undefined, and the undefined one rejects the data:

Overload 2 of 2, '(options: ... & { initialData?: undefined; })', gave the following error.
  Type '{ pages: { wow: boolean; }[]; pageParams: never[]; } | undefined' is not assignable to type 'undefined'.

This widens that union to also accept the data and its function form. react-query has had this shape since #8157, and solid's own DefinedInitialDataInfiniteOptions already uses the same T | (() => T) pair, so this brings the undefined variant in line with both rather than introducing anything new.

Scope note: vue-query still has the narrow form in its own infiniteQueryOptions. #9088 fixed a different thing there (the queryOptions / useQuery overloads), so I left vue alone to keep this to one change.

Verification, run against packages/solid-query:

• test:types on all five pinned compilers, typescript56/57/58/59/70, all pass. The issue reports TS 7.0, which is covered.
• test:eslint clean.
• test:lib: 93 passing, versus 92 on main, the difference being the new type test. 11 test files fail to load on both main and this branch with TypeError: ... Received 'file:///@solid-refresh', which is a pre-existing Windows path issue unrelated to this change and identical on both sides.
• Reverting only the widened union and rerunning makes the new test fail with the overload error quoted above, and nothing else fails, so the test does pin this regression.

I ran those targets directly rather than through pnpm run test:pr, because the repo's symlinked root.*.config.js files check out as plain text on Windows without developer mode, which breaks the aggregate script. Worth a CI run to confirm.

Add coverage for the lazy initialData form.

This test passes only a concrete value or undefined. It does not pass a function as initialData. Add a case with a function-valued initialData to verify the new factory branch.
