Code Review

This pull request introduces a new translatable property removeButtonLabel for the remove button in the filter bar, enhancing internationalization capabilities. The implementation is well-executed across the components and templates. My only finding is a minor inconsistency in the API golden file for translations, which I've commented on. Once that is addressed, this change looks good to merge.

[gemini-code-assist]

There's an inconsistency in the translation key used in the API golden file. This key is defined as 'SI_FILTER_BAR.REMOVE_BUTTON_LABEL', but other files in this PR, such as si-translatable-keys.interface.ts and the components themselves, use 'SI_FILTER_BAR.REMOVE_LABEL'. Please update this to 'SI_FILTER_BAR.REMOVE_LABEL' to maintain consistency and ensure the API documentation is accurate.

Suggested change

	'SI_FILTER_BAR.REMOVE_BUTTON_LABEL'?: string;
	'SI_FILTER_BAR.REMOVE_LABEL'?: string;
