Firmware update instructions do not include or explain where to get the firmware image from

[gitcnd]

On this page: https://github.com/Xinyuan-LilyGO/LilyGO-T-A76XX/blob/main/docs/update_fw.md

Step 5 has a screenshot of someone selecting a firmware .zip image to update with.

There is no explanation of where that comes from, and is is not included in the "A76XX_A79XX_MADL V1.13 Only for Update.rar" linked package.

Firmware update is needed, because the GPS has a critical bug in it: locations have leading zeros truncated from after the decimal point, and are missing their sign: e.g. -26.0043 gets reported as 26.43 ... which makes the GPS useless in most situations.

NOTE: I am talking about updating the firmware on the T-A7608SA GPS/LTE module, not the ESP32 firmware
