Enable the ESLint prefer-const rule in the web/ directory
Please find additional details about the ESLint rule at https://eslint.org/docs/rules/prefer-const Note that this patch is generated automatically, by using the ESLint `--fix` argument, and will thus require some additional clean-up (which is done separately).
