chore(core): Deprecate FeedbackButton FAB APIs (#5933)

* refactor(core): Rename FeedbackWidget to FeedbackForm

Deprecate "widget" term in favor of "form" to align with the broader
Sentry SDK ecosystem naming convention.

All public APIs are preserved as deprecated aliases:
- FeedbackWidget → FeedbackForm
- showFeedbackWidget → showFeedbackForm
- FeedbackWidgetProps → FeedbackFormProps
- FeedbackWidgetStyles → FeedbackFormStyles
- FeedbackWidgetState → FeedbackFormState
- FeedbackWidgetTheme → FeedbackFormTheme
- FeedbackWidgetManager → FeedbackFormManager

Closes #5892

* test(core): Add backward compatibility tests for deprecated FeedbackWidget API

Verify that the deprecated FeedbackWidget and showFeedbackWidget exports
are identical to their FeedbackForm replacements.

* chore(core): Deprecate FeedbackButton, showFeedbackButton, and hideFeedbackButton

Mark the floating action button (FAB) APIs as deprecated. They will be
removed in a future major version.
