RFR: 8296283: JUnit5 tests using Params API fails to compile

[Ambarish Rapte]

This issue was uncovered when running the test added in a PR in commit #1+#2: https://github.com/openjdk/jfx/pull/924
The JUnit5 tests using Params API fails to compile.

Fix:
Change dependency of `junit-jupiter-params` from runtime to compile time.
From: https://junit.org/junit5/docs/current/user-guide/#overview-what-is-junit-5: it can be understood that packages of JUnit Jupiter other than `TestEngine` are required for test compilation and
JUnit Platform serves as a foundation for [launching testing frameworks](https://junit.org/junit5/docs/current/user-guide/#launcher-api)

It seems that changing dependency of this one package is sufficient for this fix.
