Add tag when pushing to main

[glazychev-art]

Description

Currently, we only tag images:
ghcr.io/networkservicemesh/govpp/vpp:v23.10-rc0-166-g4a6d39d90

It is also necessary to tag the commit from which this image was built.

Action plan for including govpp into the NSM release:

1. Add vpp version tagging for commit on every push into main branch
2. Add release workflow (support usual tagging with NSM release version)
3. Don’t exclude /govpp package from go.mod dependencies (check-gomod-deps.yaml)

Example:

1. Any push into main:
   a. Tag the last commit with the last vpp version like v23.10-rc0-169-g7e1c880d6
   b. Build the govpp/vpp image and tag it with the last vpp version like v23.10-rc0-169-g7e1c880d6
2. Release:
   a. Create a release branch like release/v1.12.0
   b. Tag the last commit with a release version like v1.12.0
   c. Build the govpp/vpp image and tag it with a release version like v1.12.0

Seems like the scope is done.

Can be improved in the future #40
