Doc/Michelson: redirect operations on views to interactive reference

Context

Answers this part of #4077:

• delete the parts about instructions from the static reference:
  • Operations on views

The documentation about the operation on views is added to the interactive reference: michelson-reference!123 (merged).

Note that the view example is not being migrated to the interactive reference, but moved to the Examples section instead. That's because the examples in the interactive reference are supposed to work in https://try-michelson.com, which is not the case of the view example since it relies on the view contract that is not in the chain context.

Manually testing the MR

make -C docs -j

And then open docs/_build/alpha/michelson.html in a web browser.

Or open the exposed artifacts Documentation - excluding old protocols below, and navigate to docs/_build/alpha/michelson.html.
