STRWEB-105 lock favicons to v7.1.4 to avoid build failures (#135)

`favicons` `v7.1.5` bumps `sharp` from `v0.32.6` to `v0.33.1` and ain't
nothin' building anymore. See also itgalaxy/favicons#448.
Jenkins errors look like
```
/home/jenkins/workspace/Automation/build-platform-complete-snapshot/node_modules/favicons-webpack-plugin/src/index.js:656
    throw new Error(
          ^

Error: Could not find the npm peerDependency "favicons".
Please run:
npm i favicons
 - or -
yarn add favicons

Error: Could not load the "sharp" module using the linux-x64 runtime
Possible solutions:
- Ensure optional dependencies can be installed:
    npm install --include=optional sharp
    yarn add sharp --ignore-engines
- Ensure your package manager supports multi-platform installation:
    See https://sharp.pixelplumbing.com/install#cross-platform
- Add platform-specific dependencies:
    npm install --os=linux --cpu=x64 sharp
    npm install --force @img/sharp-linux-x64
- Consult the installation documentation:
