chore: update toolchain for GitPod

[pfeerick]

Continuation of #23, resolves #26.

How can I build 2.10.x with Gitpod now that the toolchain has been changed?

There are also problems with the EdgeTX Buddy when trying to build 2.10.6. The firmware apparently cannot be built. It keeps alternating between "Building on Server" and "in queue". Then after several minutes "Failed".

2.10 branch is now properly pinned to use 2.10 build container for GitPod... i.e. https://gitpod.io/new/#https://github.com/edgetx/edgetx/tree/2.10 should build 2.10

This looks like something might have gone wrong when @raphaelcoeffic just updated of the cache stuff, as it is chocking at some LVGL code... which it shouldn't as my standalone language builds worked for DE 🤭

correction... the main toolchain is being used by cloudbuild for everything... so anything colorlcd will break for the immediate future for 2.10
