Fix: composer scripts doesn't work on Windows

[t-hamano]

Note: I added the --no-verify option on commit to prevent the large number of diffs created by lint-staged.

This PR fixes the composer's lint/format command to work on Windows.

PS D:\path\to\create-block-theme> npm run lint:php

> create-block-theme@1.5.1 lint:php D:\path\to\create-block-theme
> ./vendor/bin/phpcs

'.' is not recognized as an internal or external command,
operable program or batch file.

As seen in the issue in the npm repository, npm scripts starting with ./ do not work on Windows. Therefore, I used composer run-script instead, as is done in the Gutenberg repository.

In addition, .phpcs.xml.dist was renamed to phpcs.xml.dist because the ruleset file name specified by the composer script does not exist.

Confirm that the following commands work:

Should show errors.

npm run lint:php

Error should appear and the code should be formatted. To restore the automatically changed format, run git checkout ..

npm run lint:php:fix

Thanks for fixing this! Sorry, this was my bad. I didn't realise scripts starting with ./ don't work on Windows.

I can confirm npm run lint:php and npm run lint:php:fix still work the same for me.
