Update gradle disable leftShift method

[josselinchevalay]

Hello,

i have this error :

* Where:
Build file 'C:\projects\cargo-with-gradle\build.gradle' line: 12

* What went wrong:
A problem occurred evaluating root project 'cargo-with-gradle'.
> Failed to apply plugin [id 'com.arielcabib.rust']
   > Could not find method leftShift() for arguments [com.arielcabib.plugin.gradle.rust.RustPlugin$_apply_closure1@76b47b3c] on task ':rustBuild' of type org.gradle.api.DefaultTask.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

so I propose my change to create task by implicit method

Regards
