customElement option throws an error

[Jeggle-s]

Describe the bug
Today I upgraded esbuild-svelte to version 0.74 with Svelte 4 as dependency. In the migration guide it states, that the Tag-Option for custom components is deprecated with Svelte 4 and was replaced with the customElement option (see https://svelte.dev/docs/v4-migration-guide#custom-elements-with-svelte). Using this new option, the esbuild-svelte plugin throws following error:

<svelte:options> unknown attribute

To Reproduce
Steps to reproduce the behavior:

1. Define a custom component tag with <svelte:options customElement="my-component">
2. Include this component in an HTML file
3. See error

Expected behavior
No error should be thrown. The error should only occur if the old option (tag) was used.

Environment:

• esbuild-svelte version: 0.7.4
• esbuild version: 0.17.5
• Svelte preprocessors used (if any): svelte-preprocess - 5.0.3

I am unable to reproduce this issue when using Svelte 4. Are you sure you have upgraded to Svelte 4 (npm install svelte@4)?

Ah damn it. I did not update all my dependencies. Error was in front of the monitor. I'm closing this issue.
