Accessibility error in tutorial

[sdserage]

Describe the bug
https://svelte.dev/tutorial/select-bindings An accessibility error occurs because on:change is being used over on:blur on the select bindings page of the Svelte tutorial.

A11y: on:blur must be used instead of on:change, unless absolutely necessary and it causes no negative consequences for keyboard only or screen reader users. (24:1)

I'm sure that this is a result to updates with accessibility, maybe worth reviewing and updating the error message or including on:blur for this section of the tutorial.

Severity
Very minor.

https://svelte.dev/tutorial/media-elements Another one here:

A11y: Media elements must have a <track kind="captions"> (111:0)

Example doesn't include track tag by default.

For reference: there's been previous PRs to fix the on:blur warning in the tutorial (#6189, #5861, #5037). There's an ongoing discussion in #4946 on whether this warning should be removed entirely, as it seems to only be relevant in very old IE (<11).

Similarly, the captions warning on the tutorial is tracked in #6158. There is discussion in #5967 on whether that warning should also be removed, since no browser supports <track> in <audio> elements.
