rhysd/actionlint v1.6.3 on GitHub

Improve guessing a type of matrix value. When a matrix contains numbers and strings, previously the type fell back to any. Now it is deduced as string.
```
strategy:
  matrix:
    # matrix.node is now deduced as `string` instead of `any`
    node: [14, 'latest']
```
Fix types of || and && expressions. Previously they were typed as bool but it was not correct. Correct type is sum of types of both sides of the operator like TypeScript. For example, type of 'foo' || 'bar' is a string, and github.event && matrix is an object.
actionlint no longer reports an error when a local action does not exist in the repository. It is a popular pattern that a local action directory is cloned while a workflow running. (#25, #40)
Disable SC2050 shellcheck rule since it causes some false positive. (#45)
Fix -version did not work when running actionlint via the Docker image (#47).
Fix pre-commit hook file name. (thanks @xsc27, #38)
New branch_protection_rule event is supported. (#48)
Update popular actions data set. (#41, #48)
