explicit ajv stack error

[Lausselloic]

Reasons for making this change

Improve the error format from AJV. Currently it return a dotted path from schema like .foo.bar.mycustomProp is a required property into the stack error. What I ropose is to fetch "display" name of the property if it exists title or the property himself otherwise. It's more human readable and it's whats is needed for a user interface I think.

Related to #1337 need to enbale verbose mode of AJV

User could still create the old message by using Property and message returned into the error field

If this is related to existing tickets, include links to them as well. Use the syntax fixes #[issue number] (ex: fixes #123).

@epicfaace if we bump the major version for my PR, maybe adding this one in at the same time makes sense?

@Lausselloic in the upcoming @rjsf v5 release the utils.js and validator.js files have been refactored into their own packages (see the rjsf-v5 branch). If you feel that this change is critical, I encourage you to port it onto that branch.

@Lausselloic So the v5 beta is now the master branch... Please consider porting this to the validator-ajv6 and validator-ajv8 packages.
