install pcregrep before use it

[CitraIT]

Hi,
i'm using this script to install NxFilter on OPNsense v24.x.
It worked on older versions, but the script is failing at latest version where pcregrep executable is not found (not installed by default).

Olá pessoal!
Precisamos instalar/habilitar o NXFilter no PFSense nas suas versões mais atualizadas.Estamos cientes da incompatibilidade JAVA.
PFSense 2.7.2 + NXFilter 4.6.9.8

Seguimos os procedimentos oficiais através o script recomendado pelos caminhos oficiais do NXfilter:
https://tutorial.nxfilter.org/search.php?kw=pfsense

Sempre utilizamos este script com sucesso, inclusive existe uma observação referente solução de contorno da compatibilidade java como o FreeBSD, mas não funciona:

Se alguém souber uma luz, agradeço!

Hello!
We have dozens of customers in the same scenario.
We need to install/enable NXFilter in PFSense in its most updated versions.

We are aware of the JAVA incompatibility.
PFSense 2.7.2 + NXFilter 4.6.9.8

We follow the official procedures through the route recommended by the official NXfilter paths:
https://tutorial.nxfilter.org/search.php?kw=pfsense

We have always used this script successfully, there is even a note regarding the workaround for Java compatibility with FreeBSD, but it does not work:

If anyone has a light, thanks!
