SpringBoot Wrapper types are not displayed in actuator env endpoint

We have upgraded on off our projects at work to Spring boot 2.4. It seems like the way properties are serialized under /actuator/env had changed.

For example we used to be able to get the server.port like this:

...
"properties": {
   "local.server.port": {
   "value": 1660
   }
}
...

After upgrading it instead looks like:

...
"properties": {
   "local.server.port": {
   "value": "Complex property type java.lang.Integer"
}

I tracked it to this recent commit: https://github.com/spring-projects/spring-boot/commit/1a3f810cd88ce9933fe862df1f2907a4dd12a4cf

I think the method stringifyIfNecessary should have branches for all the standard boxed types as well as BigDecimal and BigInteger.

To reproduce you can spin up a standard project from https://start.spring.io/ and include "Spring Web" and "Spring boot actuator" as dependencies and then visit the env endpoint.
