fix: allow attributes on the title element

The spec states the title element supports global attributes. https://html.spec.whatwg.org/#the-title-element

Reverts the title attribute validation introduced in #1721.

Fixes #5198.

Before submitting the PR, please make sure you do the following

• [x] It's really useful if your PR references an issue where it is discussed ahead of time. In many cases, features are absent for a reason. For large changes, please create an RFC: https://github.com/sveltejs/rfcs
• [x] Prefix your PR title with feat:, fix:, chore:, or docs:.
• [x] This message body should clearly illustrate what problems it solves.
• [x] Ideally, include a test that fails without this PR but passes with it.
• [x] If this PR changes code within packages/svelte/src, add a changeset (npx changeset).

Tests and linting

The test plan is to re-use packages/svelte/tests/validator/samples/title-no-attributes. By removing errors.json, we test that svelte compiles the title element with attributes.

• [x] Run the tests with pnpm test and lint the project with pnpm lint

The tests pass, but pnpm lint failed with:

> [email protected] lint /opt/p/svelte
> eslint && prettier --check .
