fix(bug): create /usr/local/bin if not present

[schmikei]

Description of Changes

• Some installations(notably default M1 macOS 12) do not have the folder /usr/local/bin present when they run the installer. So this PR addresses this by ensuring the directory exists before linking the installed binary to the $PATH

Tested on linux by removing the /usr/local/bin and rerunning the installer whereas on main it failed.

From my understanding it is the responsibility of the third party app in the macOS ecosystem to create the folder if it wishes to add things to /usr/local/bin https://discussions.apple.com/thread/252495484

Please check that the PR fulfills these requirements

• Tests for the changes have been added (for bug fixes / features)
• Docs have been added / updated (for bug fixes / features)
• CI passes

Do we even want to put a link in this directory if it doesn't exist? I imagine this is to make it so that stanza is on your path, does creating the directory and linking actually do that on the affected systems?

Sudo is always required for Linux, and will be required for macos if the user does not have write permission to /usr/local/bin.

I agree with this generally, just am thinking about any current users that maybe built automation around expecting it being in /usr/local/bin. That is the only argument I have for the link in the first place, perhaps in the future we make a more definitive call on whether or not installations add to /usr/local/bin in the first place, but I just wanted to not introduce any potential regressions at this moment.
