[BUG] --help output out of date

[Artos254]

Describe the bug
--help output states os name can be used in the --os argument, this is no longer the case. Supplying "Tahoe" instead of "26" causes the script to not discover the version of InstallAssistant to download.

To Reproduce

• /Library/Management/erase-install/erase-install.sh --reinstall --replace-invalid --os Tahoe --check power --min-battery 30 --no-timeout --check-power --power-wait-limit 900 --max-password-attempts infinite --rebootdelay 120 --postinstall-command "jamf recon" vs /Library/Management/erase-install/erase-install.sh --reinstall --replace-invalid --os 26 --check power --min-battery 30 --no-timeout --check-power --power-wait-limit 900 --max-password-attempts infinite --rebootdelay 120 --postinstall-command "jamf recon"
• Standalone in Terminal

Expected behavior
See above, covered already.

Code/log output
Please supply the full command used, and if applicable, add full output from Terminal or from /var/log/erase-install.log. Don't post a partial log - I need the whole thing. Either upload the log as a file, or paste the output in a code block like this:
