bazel: update available to 6.0.0

[kickingvegas (Charles Choi)]

In MacPorts, the current version of bazel is at 4.2.2 <​https://ports.macports.org/port/bazel/details/>

However, the current release of bazel is at 6.0.0 as of 2023-03-04. <​https://github.com/bazelbuild/bazel/releases/tag/6.0.0>

Request is to please update bazel to 6.0.0 on MacPorts.

In particular this is driven by desire to support building swiftlint <​https://github.com/realm/SwiftLint> using tools from MacPorts which in this case, includes bazel.

Any updates?

Bazel has been updated to 6.1.2 for about a week at this point: ​https://ports.macports.org/port/bazel/

Hello! While I appreciate the update of the Bazel port, I think it would be prudent to update its dependencies which are quite old as well. Currently it is set as follows:

--->  Computing dependencies for bazel
The following dependencies will be installed: 
 openjdk11-zulu
 python27
 python2_select

Reopending this ticket to update its dependencies. Thank you for your efforts!

According to the Bazel documentation ( ​https://bazel.build/install/compile-source ), JDK 11 is required:

2.1. Install the prerequisites

- Bash

- zip, unzip

- C++ build toolchain

- JDK. Version 11 is required.

- Python. Versions 2 and 3 are supported, installing one of them is enough.

Also in bazel's Portfile, it's indicated that both Python 2 and 3 are required.
