Manage cdi-api at version 1.2

This avoids a conflict where:

1. org.sonatype.sisu:sisu-inject-bean:2.6.0
   depends on javax.enterprise:cdi-api:1.0
   depends on javax.annotation:jsr250-api:1.0
2. org.eclipse.jetty:jetty-annotations:9.4.26.v20200117
   depends on javax.annotation:javax.annotation-api:1.3

with jsr250-api and javax.annotation-api having the same classes.
