Documentation: fixedWidth deprecation notice is confusing for v6.7.0+ users

[bisonhubert]

Describe the bug
The fixedWidth prop deprecation notice in v6.7.2 type definitions states "@SInCE 7.0.0" but the prop doesn't work in v6.7.0+. Users are left unclear about what changed and when. Here is a link to the documentation:

react-fontawesome/src/types/icon-props.ts

Lines 37 to 50 in 97fdfaa

	/**
	* @deprecated
	* @since 7.0.0
	*
	* Starting in FontAwesome 7.0.0, all icons are fixed width by default.
	* This property will be removed in a future version.
	*
	* If you want to remove the fixed width to replicate the behavior of
	* previous versions, you can set the new {@link widthAuto} property to `true`.
	*
	* @see {@link FontAwesomeIconProps.widthAuto}
	*/
	fixedWidth?: boolean | undefined
	/**

Reproducible test case
View the JSDoc comment in @fortawesome/react-fontawesome type definitions (index.d.ts) for the fixedWidth prop in v6.7.2+.

Expected behavior
The deprecation notice should clarify what actually changed in v6.7.0+ and why fixedWidth no longer works, rather than referencing @deprecated @since v7.0.0.

Desktop (please complete the following information):

• Browser: Brave 1.85.118 (Official Build) (arm64), Firefox 146.0.1 (aarch64)
• Version: react-fontawesome v3.0.2, @fortawesome/fontawesome-svg-core v6.7.2

Additional context
The current message creates confusion about whether the behavior changes in v6.7.0 or v7.0.0, and doesn't explain why fixedWidth is non-functional in v6.7.2.
