    .SYNOPSIS
    Parses a .env file and sets environment variables from it.

    .DESCRIPTION
    This function reads a .env file, parses each line as a key-value 
    pair, and sets corresponding environment variables within the current
    PowerShell session. The .env file format should have one key-value 
    pair per line, separated by an equals sign (=).

    .EXAMPLE
    Set-EnvVarsFromDotEnv -Path '.env'

    This will read the .env file in the current directory and set the
    environment variables defined within it.

    .PARAMETER Path
    The path to the .env file to be parsed. If not provided, defaults
    to '.env' in the current directory.
