Merge branch '24754-fix-npm-warnings-for-eslint-plugin-import' into 'master'

Fix NPM install warnings due to incompatible dependency version

## What does this MR do?

Rolls back `eslint-plugin-import` to semver `^1.16.0` for compatibility with `eslint-config-airbnb`.

## Are there points in the code the reviewer needs to double check?

Shouldn't be.

## Why was this MR needed?

A warning message was being generated every time we run `npm install`, and there are possibly other side effects due to module incompatibility.

## Does this MR meet the acceptance criteria?

- [x] All builds are passing
- [x] Branch has no merge conflicts with `master` (if it does - rebase it please)

## What are the relevant issue numbers?

Closes #24754
