Subject: [PATCH] Enable the ESLint `no-unsafe-optional-chaining` rule

Given that we're using optional chaining in the code-base, see https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Optional_chaining, it can't hurt to add this ESLint rule to help catch one possible source of bugs when using optional chaining expressions.

Please find additional details about the ESLint rule at https://eslint.org/docs/rules/no-unsafe-optional-chaining
