[Examples] Issues running examples about cosmic-text

[phsilva]

One additional comment on the example is that they don't follow regular cargo examples structure. Although examples are a top-level folder, the following fails:

cargo run --example terminal

it says there are no example named terminal, because on the main Cargo.toml examples are included as members of the workspace, which works of course, but creates a a learning curve by not following the standard cargo structure for examples.

Just for reference, to run example you need:

cargo run --package terminal

I am also having issues running the example on MacOS. the terminal one was the only one that worked.
