Idea: Create a separate page for schedulers (under Reference)

During the scheduling meeting today, it came up that our swappable runtime schedulers for the C and Python targets might merit their own dedicated page under Reference, similar to Tracing.

#80 added a concise explanation for these schedulers. However, a lot more can be said about each scheduler, including details about their internal structures, execution strategies, how they perform relative to each other, what kind of applications might benefit from each, etc.

This page could also serve as a way to keep a record of our progress on developing these schedulers as we add more of them.

This page would also be a great place to explain the task set generator tool (lf-lang/examples-lingua-franca#3).

Start by reviewing the concise scheduler explanation added in issue #80 and the existing Reference/Tracing page structure. Define a dedicated scheduler page covering the C and Python scheduler structures, execution strategies, relative performance, suitable applications, development progress, and the task set generator from lf-lang/examples-lingua-franca#3. Done means the new page is placed under Reference and provides this documented overview.
