fix(scoop-download|install|update): Use consistent options

[lewis-yeung]

Description

This PR is to fix a bug: the shorthand of the option --no-hash-check for the command scoop download should be -s instead of -h to be consistent with scoop install and scoop update, since the flag -h always means printing help text for a command.

BTW, the option --no-hash-check for scoop download is also inconsistent with --skip for scoop install or scoop update, even though they work the same way. For backwards compatibility, I did not adjust it. Should we?

EDITED: Use consistent options (-s/--skip-hash-check) for scoop download, scoop install and scoop update.

How Has This Been Tested?

- Run scoop download -h, and it prints the help text for us.
- Run scoop download -s <app>, and it skips the hash verification after the download, which is the expected behavior.

1. Run the following to check available CLI options in the help text:

   • scoop download -h
   • scoop install -h
   • scoop update -h

2. Run the following to skip hash validation:

   • scoop download -s <app>
   • scoop download --skip-hash-check <app>
   • scoop install -s <app>
   • scoop install --skip-hash-check <app>
   • scoop update -s <app>
   • scoop update --skip-hash-check <app>

Checklist:

• I have read the Contributing Guide.
• I have ensured that I am targeting the develop branch.
• I have updated the documentation accordingly.
• I have updated the tests accordingly.
• I have added an entry in the CHANGELOG.

Prefer renaming all args to --skip-hash-check w/ -s.
