Initial support for macOS 26 Tahoe

[perez987]

With these few changes, at least Tahoe can be seen in the list of installers available for download.
But there's still work to be done on the icons:

• App Icon Preview - Tahoe is still the Sequoia icon; it's not easy to create the new icon with Tahoe colors in the background of the letter m.
• Application - macOS Tahoe is also the Sequoia icon.

Note that the Tahoe installer 25A5327h is duplicated. This is due to Apple's changes to the version repository, as this duplicate is also visible in Download Full Installer and gibMacOs. All three apps are missing the latest version, 25A5338b. I don't know why.
