🩹 [Patch]: Update module requirements and function calls that use Ast (#86)

## Description

This pull request includes updates to the `Set-ScriptFileRequirement`
function in the
`src/functions/public/PowerShell/Module/Set-ScriptFileRequirement.ps1`
file. The most important changes involve updating module requirements
and modifying function calls.

Updates to module requirements and function calls:

* Updated the required version of the `Ast` module from `0.2.3` to
`0.3.0`. Note: The module holding the Ast* functions was renamed from
`AST` to `Ast`.
* Replaced calls to `Get-FunctionName` with `Get-ASTFunctionName` within
the `Set-ScriptFileRequirement` function to reflect the updated module
usage.
