[Security Solution] Updating generator to install/update the endpoint package during setup

[jonathan-buttner]

Fleet no longer installs the endpoint package by default when the /setup API is requested (#102219). The resolver generator relied on /setup installing the endpoint package so that the mappings would be in place before it sent data to Elasticsearch. This PR adds functionality to the generator to install/update the endpoint package directly during the scripts setup.

I was hoping to do a gif but it was taking too long to record the whole process haha.

Example run

yarn test:generate -f -s resolver --gen 3 --pr 100 --pt 100 --delete
yarn run v1.22.10
$ node scripts/endpoint/resolver_generator -f -s resolver --gen 3 --pr 100 --pt 100 --delete
