Make @unpinned_maven//:pin always visible

[dmivankov]

Allows to run :pin via multirun target regardless of strict visibility setting

Use-case is still to run it a a part of manual command, like

# TODO: fix multirun handling of *_binary.args, it just exec-s files_to_execute at the moment
load("@com_github_atlassian_bazel_tools//multirun:def.bzl", "command", "multirun")
command(
    name = "pin-update",
    arguments = ["$(rootpath //:jq)"],
    command = "@unpinned_maven//:pin",
    data = ["//:jq"], # may also try using jq from rules_jvm_external
)
multirun(
    name = "maven-update",
    commands = [
        ":pin-update",
        ":some-other-update-task", # for example update checked-in generated pom.xml that can trigger dependabot PRs/alerts
        ":maybe a task that reports something",
    ]
)

Making pin public may also allow using it at build or test time, bur probably not that useful unless it starts accepting arguments like target maven_install.json location

Thank you for the PR!

I'm just trying to understand what the use-case for this is: I've always imagined that the pin target is run by a user on the command-line, but this suggests your doing something else. Could you please edit the commit message to explain why this would be useful to someone? I'd be very happy to merge this after that change is made!

Added an example 👍
