🩹 [Patch]: Update environment variable prefixes for GitHub script inputs

[MariusStorhaug]

Description

This pull request focuses on updating environment variable names across multiple scripts to ensure consistency and clarity. The changes involve renaming variables from GITHUB_ACTION_INPUT_* to PSMODULE_GITHUB_SCRIPT_INPUT_*. This is to reduce the change of clobbering the envvars for the GitHub-Script action. Aligns with a undocumented decision of having all inputs of actions and workflows as <OWNER>_<REPO_NAME>_INPUT_*.

• Fixes 🩹 [Patch]: Rename the env vars for the action #36

As this is internals of the action, this is deemed a patch update as nothing should rely on these variables apart from the scripts in the action.

• Updated environment variable names in action.yml to use the PSMODULE_GITHUB_SCRIPT_INPUT_* prefix.
• Modified scripts/info.ps1 to reflect the new environment variable names for ShowInfo, Token, and Debug settings. [1] [2] [3]
• Adjusted scripts/init.ps1 to use the updated environment variable names for ShowInit, Version, Prerelease, Token, ClientID, and PrivateKey. [1] [2] [3]
• Changed scripts/outputs.ps1 to use the new environment variable name for ShowOutput.
