Use Spring Boot 2.3.4 for Demo project

[sixdouglas]

Description

This PR is to upgrade the Spring Boot version used for the demo project.

• Relevant Issues :

As you can see, in the following files :

karate-demo/src/test/java/demo/error/no-url.feature
karate-demo/src/test/java/demo/headers/content-type.feature

I've removed the test looking for charset=UTF-8, since Spring Consider this as the default value and marked his MediaType#APPLICATION_JSON_UTF8 as deprecated ( See here ). As compiler is launched with the -Werror flag, forcing the server to send this header, would fail the build.

• Type of change :
  • New feature
  • Bug fix for existing feature
  • Code quality improvement
  • Addition or Improvement of tests
  • Addition or Improvement of documentation

@sixdouglas this is great, thanks. the build does seem to have failed, hopefully just a minor tweak away: https://travis-ci.org/github/intuit/karate/builds/732896653

I'm building the project using this command:

mvn clean package -P pre-release -Dmaven.javadoc.skip=true -B -V -Djavacpp.platform=linux-x86_64

I'm running the Build locally and it fails in the karate-robot module with this:

[ERROR] Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 0.12 s <<< FAILURE! - in com.intuit.karate.robot.OpenCvUtilsTest
[ERROR] testOpenCv(com.intuit.karate.robot.OpenCvUtilsTest)  Time elapsed: 0.12 s  <<< ERROR!
java.lang.UnsatisfiedLinkError: no jniopenblas_nolapack in java.library.path
	at com.intuit.karate.robot.OpenCvUtilsTest.testOpenCv(OpenCvUtilsTest.java:22)
Caused by: java.lang.UnsatisfiedLinkError: no openblas_nolapack in java.library.path
	at com.intuit.karate.robot.OpenCvUtilsTest.testOpenCv(OpenCvUtilsTest.java:22)

But there are no error in the karate-demo module.
Do you have any idea on how I can fix this issue?

Otherwise, the build run successfully without the -Djavacpp.platform=linux-x86_64 option

I retried on CI still failed. but no worries, let me investigate locally
