Respect .github/pinact.yaml as the default config

Feature Overview

Respect .github/pinact.yaml as the default config.

Why is the feature needed?

Please explain the problem you want to solve.

• Reduce dotfiles from the repository root.
• Place files under the directory that is used by the context.

I put the config under .github, that is clear for GitHub-specific files.
Currently, pinact needs to specify the config path to read, but this path pattern is a very standard use case like renovate.json did.

In .github, the dot prefix is needless. So I perfectly agree with this example path - .github/pinact.yaml.

Example Code

command and configuration

$ pinact init '.github/pinact.yaml'
$ pinact run
