Merge pull request #5206 from Homebrew/dependabot/bundler/Library/Homebrew/test/parallel_tests-2.26.2

Bump parallel_tests from 2.26.0 to 2.26.2 in /Library/Homebrew/test

dev-cmd/bottle: require arg for --root-url

This issue causes method in a Nil object to be read when a mirror download fails. In my case, this occurs due to my office's proxy blocking certain mirrors. This patch fixes the Nil access, exposing a more helpful error message.

## Before patch
```
$ brew install maven
Error: An exception occurred within a child process:
  NoMethodError: undefined method `unlock' for nil:NilClass
```

## After patch
```
$ brew install maven
Error: An exception occurred within a child process:
  DownloadError: Failed to download resource "maven"
Download failed: Couldn't determine mirror, try again later.
```

## Steps to reproduce
1.  Use brew 1.8.0
2.  Ensure maven is not installed:
    ```
    brew remove maven
    ```
3.  Ensure the download is not cached:
    ```
    rm "$HOME/Library/Caches/Homebrew/downloads/*--apache-maven-*-bin.tar.gz"
    ```
4.  Make the mirrors unreachable by pointing them at a nonfunctional proxy:
    ```
    export http{,s}_proxy=http://localhost:8080
    export no_proxy=*.github.com,*.brew.sh
    ```
5.  Attempt package installation
    ```
    brew install maven
    ```

Set HOMEBREW_FORCE_BREWED_CURL or HOMEBREW_FORCE_BREWED_GIT if the system-provided versions are missing or outdated, causing either to be installed on the next `brew update`.

diy: add meson support

Also print the path to put files into if no build system was
determined.

Welcome!

audit: make `keg_only_style` non-strict

options_cop: make audits non-strict

audit: remove deleted formulae from unstable whitelist

unpack_strategy: fix extension for compress

audit: make `throttled` a regular audit

Note that the `HOMEBREW_FORCE_BREWED_` vars are automatically set if the system `git` and `curl` are too old. Drop mention of `HOMEBREW_GIT` which isn't user-settable.

Ensures `system` and `safe_system` use brewed git if available.
