devel/gradle6: New port

devel/gradle needs to be updated to 7.x, while some ports build failed
under the newer version, including:

- biology/jalview
- biology/igv

Updated them to use this devel/gradle6 until they officially support 7.x.
No functional changes for these ports.

+Gradle is build automation evolved.
+
+Gradle can automate the building, testing, publishing, deployment
+and more of software packages or other types of projects such as
+generated static websites, generated documentation or indeed anything
+else.
+
+Gradle combines the power and flexibility of Ant with the dependency
+management and conventions of Maven into a more effective way to
+build. Powered by a Groovy DSL and packed with innovation, Gradle
+provides a declarative way to describe all kinds of builds through
+sensible defaults. Gradle is quickly becoming the build system of
+choice for many open source projects, leading edge enterprises and
+legacy automation challenges.
