docs: use the dynamic README header endpoint

[AlemTuzlak]

Adopts the dynamic README header endpoint added in TanStack/tanstack.com#1076,
which is merged and live.

Every README banner in this repo now points a <picture> at
https://tanstack.com/api/readme/ instead of a committed PNG. The endpoint
renders 1800x450 in light and dark, so a branding change lands in every README
at once and dark-mode readers get a dark banner.

What changed

• 1 README(s) updated.

• Light and dark served through <picture>, per GitHub's guidance. The trailing <img> stays the light variant, as the fallback for renderers that ignore <picture> (npm, most editors).

• Deletes the now-unused media/header_store.png.

Verification

Every generated URL in this diff was requested against the live endpoint and
returned 200 image/png at 1800x450. git grep confirms no README still
references the old media/header_*.png path.

Heads up: deleting the committed PNG means npm pages for already-published
versions that embed the raw.githubusercontent.com/.../main/media/header_*.png
link will show a broken image, since that link is branch-pinned. New releases
pick up the endpoint URL.

Summary by CodeRabbit

• Documentation
  • Updated the Store header image to adapt responsively to light and dark color schemes.
