.SYNOPSIS
    Checks if a directory exists, clones it if not, and changes to it.

.DESCRIPTION
    The Clone-OrCdToDirectory function checks if the specified directory exists.

    the repository if necessary.

.PARAMETER Path
    Specifies the path of the directory to check or clone.

.PARAMETER RepositoryURL
    Specifies the URL of the repository to clone from if the directory doesn't exist.

.EXAMPLE
    Clone-OrCdToDirectory -Path "nushell" -RepositoryURL "https://github.com/nushell/nushell.git"

    This command checks if the "nushell" directory exists. If it doesn't, it clones the
    repository from the specified URL. If it does exist, it changes to the directory
    and updates the repository.
