[PATCH v3] docs: freebsd: Update to 20.11

[David Young <dave@youngcopy.com>]

This patch updates the FreeBSD DPDK installation guide to detail
how users can find and install specific versions of DPDK using the
pkg package manager. The prior instructions did not highlight 
'dpdk' is an alias and may not always point to the latest DPDK 
version. The guide now includes steps to search for available DPDK versions
with pkg search dpdk, select a desired version, and install that 
version explicitly with pkg install <package-name>. The <package-name>
should be replaced with the specific DPDK version, like dpdk20.11.8. 
The document includes a reminder to regularly update repositories using
pkg update to maintain access to the most recent DPDK versions.
