chore: change name of integ test snapshot directories in preparation …

…of multi-language integration tests (#22716)

To support multi language integration tests better (see #22521), we need to rename the snapshot directories. Other languages have different naming conventions, so it's not trivial anymore to generate a "nice" name just from a test file. Instead we now use the full filename. This new pattern is inspired by Jest etc that all use the full filename. 

E.g. `my-test-name.integ.snapshot` -> `integ.my-test-name.js.snapshot` 

This PR changes the code generating the snapshot names and then does the rename in one go via the following commits:
* chore: change code for generating the integ test snapshot directory names
* chore: rename test data in `integ-runner`
* chore: update `.gitignore` files with new snapshot patterns
* chore: rename all integ-test snapshots 
* chore: update integ test snapshot paths in docs
* chore: update `.npmignore` files with new snapshot pattern
* chore: update prlinter to detect new snapshot pattern

Review by commit ([start here](a884681)). The [middle commit](fee824d) contains most of the renames, is HUGE and takes a long time to load in the GitHub UI. However it only contains renames (use `--diff-filter=r` to exclude renames from the diff):
```
> git show --diff-filter=r fee824d
(empty result)
```

If you are developing a new integration test or for some other reason want to work on a single integration test over and over again without running through all the integration tests you can do so using `yarn integ integ.test-name.js`
    Remember to set up AWS credentials before doing this.
