Update to node16 and bump actions core

[snowiow]

Hi I'm recreating the PR from here to get rid of the deprecations that are currently shown in GitHub Actions. This should be released until the 31 of May, otherwise every workflow using this action will stop working. See here for the announcement of GitHub.

Issue #, if available: https://github.com/aws-actions/aws-codebuild-run-build/issues/109

Description of changes:

• Updates package.json dep @actions/core to version ^1.10.0
• Updates action.yml to node16
• Use newest versions of actions themselves

I've released this change in a new version -- v1.0.7

Thanks again!

@taoyong-ty the distributable index.js doesn't seem to be up to date with what should be the current state. In dist/index.js the setOutput function still looks like this:

function setOutput(name, value) {
    command_1.issueCommand("set-output", { name }, value);
}

but the function in @actions/core version 1.10.0 now looks like this:

function setOutput(name, value) {
    const filePath = process.env['GITHUB_OUTPUT'] || '';
    if (filePath) {
        return file_command_1.issueFileCommand('OUTPUT', file_command_1.prepareKeyValueMessage(name, value));
    }
    process.stdout.write(os.EOL);
    command_1.issueCommand('set-output', { name }, utils_1.toCommandValue(value));
}

This causes the warning to still appear. Is there something wrong in the release process? Because the file was at least updated, but not with what is expected.

Ok those were only some formattings from my commit and there is no actual release action. I provided the updated dist/index.js in this PR
