fix: bump Groovy to 5.0.5 with GROOVY-11907 workaround

Groovy 5.0.4+ bundles ASM 9.9.1 which rejects the invalid bytecode
generated by TraitReceiverTransformer for @CompileStatic traits with
static fields when method-level DYNAMIC_RESOLUTION is present
(GROOVY-11907, a regression from GROOVY-11817).

The only affected trait in grails-geb testFixtures is ContainerSupport
(static fields: container, downloadSupport). Switch it from
@CompileStatic to @CompileDynamic so its helper class compiles via
the dynamic code path, which generates valid bytecode. ContainerGebSpec
retains @CompileStatic - its delegate stubs are simple forwarding calls
unaffected by the bug.

This unblocks the Groovy 5.0.3 -> 5.0.5 upgrade. Revert to
@CompileStatic once the Groovy fix (apache/groovy#2443) ships.
