Fix and pin dependencies to unblock CI (#670)

## Changes

* Introduce the minimal set of changes to make CI pass again for the
first time since the last successful build in 2021.
* Update some of the pinned dependencies:
    * macOS executor 12.2.0 -> 16.2.0;
    * CMake 3.18.6 -> 3.31.5;
    * alpine (on x86_64) 3.13.5 -> 3.21.2.
* Pin some dependencies to avoid introducing compatibility issues:
    * cpplint to 1.5.5;
    * markdown-cli to 0.37.0.
* Update the googletest branch `master` -> `main`.
* Use the official `wolframresearch/wolframengine` Docker image instead
of the custom one.
* Increase the timeout for Wolfram Language tests 10 min -> 20 min.

## Comments

* cpplint is pinned to 1.5.5 because newer versions require headers to
be in a directory by default. The refactor will be done in a separate
PR.
* `markdownlint-cli` is pinned to 0.37.0 because newer versions require
alt text for images by default. The alt text will be added in a separate
PR.
* Wolfram Language version is kept at 12.3.0. It will be upgraded in a
separate PR.

## Examples

Observe CI now passing:
