Document that Undertow's record-request-start-time server option must be enabled for %D to work in access logging

[JCass149]

In this paragraph it is stated:

Access logging for Undertow can be configured in a similar fashion, as shown in the following example:

server:
  undertow:
    accesslog:
      enabled: true
      pattern: "%t %a %r %s (%D ms)"

However, the %D RESPONSE_TIME exchange attribute does not work "out of the box" with Spring Boot (at least for me with spring-boot-starter-parent 2.3.8.RELEASE).

I needed to also add the following:

server
  undertow:
    options:
      server:
        record-request-start-time: true

Should the docs be updated to reflect this?

Thanks :)
