Use of un-exported interface InternalizeRefs

[valentinegu]

Hello Team,

I have a use-case requiring me to overload the current RefString\RefPath functions,
In my use case the ref may contain non-ascii chars and my overload hashes Ref field.
up to v0.125.0 my use-case was possible since InternalizeRefs signature was:

kin-openapi/openapi3/internalize_refs.go

Line 394 in 43846d5

func (doc *T) InternalizeRefs(ctx context.Context, refNameResolver func(ref string) string) {

which allowed overloading refNameResolver function,

Current implementation:

kin-openapi/openapi3/internalize_refs.go

Line 493 in 1a2712f

func (doc *T) InternalizeRefs(ctx context.Context, refNameResolver func(*T, componentRef) string) {

uses the componentRef which isn't exported, as a result my use-case isn't really possible (apart of doing major reimplementation),
Is there am option to export this interface thus allowing me to achieve previously possible behavior?
