[TASK] Update typescript-eslint to 7.15

Version 7.15 officially supports TypeScript 5.5, which we use
since #104189 and therefore eliminates a build-time warning.

Also update TypeScript from 5.5.2 to 5.5.3, while at it.

Executed commands:

  npm install --save-dev \
    @typescript-eslint/eslint-plugin@^7.15 \
    @typescript-eslint/parser@^7.15 \
    @typescript-eslint/typescript-estree@^7.15 \
    typescript@^5.5.3
  npm run build-js
