Request: enhance documentation in regards to uninstall instructions (libre2.so.11 error)

[remkolems]

Just updated to pfSense+ v23.09.1 with previously installed Crowdsec v0.0.4 (https://github.com/crowdsecurity/pfSense-pkg-crowdsec/releases/tag/v0.0.4).

Followed instructions at https://docs.crowdsec.net/docs/next/getting_started/install_crowdsec_pfsense/#uninstalling

These steps provided was not sufficient enough to install v0.1 successfully.

pfSense Status Logs error message: //etc/rc.packages: The command 'cscli machines delete pfsense 2>/dev/null' returned exit code '1', the output was 'ld-elf.so.1: Shared object "libre2.so.11" not found, required by "cscli"'

Removal of re2 and abseil is required, before any new (re-)install of Crowdsec v0.1, if Crowdsec was previously installed.
