[16][Doc] account_invoice_transmit_method - Update README to Clarify Invoice Transmission Methods

[fcvalgar]

Description:

The current README for the account_invoice_transmit_method module does not clearly explain the impact of selecting different invoice transmission methods, especially regarding the "Post" method, which disables the "Send by Email" button. This has led to some confusion for users who may not be aware of how to re-enable the button after selecting "Post."

Proposed Update:

Add a section explaining that when the "Post" method is selected, the "Send by Email" button is disabled.
Include instructions on how users can re-enable the button by selecting a different invoice transmission method.
This clarification will improve the user experience by providing clear guidance on how to handle the different transmission methods.

Steps to Reproduce:

1. Go to the invoice form and select "Post" as the transmission method.
2. Observe that the "Send by Email" button is disabled.
3. To re-enable the button, change the transmission method to something other than "Post."

Expected Behavior:

Users should be aware that selecting "Post" disables the "Send by Email" button and that it can be re-enabled by modifying the transmission method.

Version Information:

Module version: 16.0
Odoo version: 16.0

I agree with any improvement of any README in the OCA.
