build: update tsconfig ECMAScript version to ES2023

With Node.js v20 now the minimum supported version for Angular v20, the
ECMAScript version used with TypeScript can be increased to ES2023. This
change applies to the build process for the CLI packages themselves and
is not related to the configuration used within projects.
