    <#
        .SYNOPSIS
            Retrieves balance sheet growth data for a specified company using the Financial Modeling Prep API.

        .DESCRIPTION
            The Get-FMPBalanceSheetGrowth function fetches detailed growth rates for various balance sheet items
            such as total assets, total liabilities, total equity, cash and equivalents, and other key financial metrics.
            This helps investors analyze a company's financial position trends over time. Users can specify which reporting
            period to retrieve growth data for and limit the number of results. If no API key is provided,
            the function attempts to retrieve it using the Get-FMPCredential function and prompts the user if necessary.

        .PARAMETER Limit
            Specifies the maximum number of growth records to retrieve. The default value is 5.

        .PARAMETER ApiKey
            Specifies your Financial Modeling Prep API key. If omitted, the function attempts to retrieve it using Get-FMPCredential.

        .EXAMPLE
            Get-FMPBalanceSheetGrowth -Symbol AAPL -Period FY -Limit 5

            This example retrieves the 5 most recent annual balance sheet growth records for Apple Inc.

        .EXAMPLE
