Added better linting support inside of the sequence adaptation

[cohansen]

This PR changes the sequence adaptation API in the following way to add linting to both the input and output format.
It also changes the diagnostics to now work as intended so that the adaptation can fully overwrite existing diagnostics rather than them always being appended.

   inputFormat: {
+   linter: globalThis.SequenceAdaptation?.INPUT_FORMAT?.LINTER ?? undefined,
   },
- lint: globalThis.SequenceAdaptation?.LINT ?? undefined,
   outputFormat: {
+   linter: globalThis.SequenceAdaptation?.OUTPUT_FORMAT?.LINTER ?? undefined,
   },

Here's a custom adaptation that you can fiddle with to test the input / output linting:

(() => {
  globalThis.SequenceAdaptation = {
    INPUT_FORMAT: {
      LINTER: inputLinter,
      NAME: "Input Format",
    },
    OUTPUT_FORMAT: {
      LINTER: outputLinter,
      NAME: "Output Format",
    },
  };
})();

function inputLinter(diagnostics, commandDictionary, view, node) {
  diagnostics.push({
    actions: [],
    from: 0,
    message: `This is a custom linting error that appears at 0,0`,
    severity: 'error',
    to: 0,
  });

  return diagnostics;
}

function outputLinter(diagnostics, commandDictionary, view, node) {
  // This is an example of overwriting all of the existing lint errors from native Aerie.
  diagnostics = [];

  return diagnostics;
}
