Code review comment for ~jugmac00/lpci:add-golang-plugin

I was not sure whether it makes sense to enter any invalid value to the version field, as the validator converts everything to string and in case that was not a valid golang version, the user gets a proper message in the error log.

I could add e.g. a value of `[1.18]` to the version field, which is not valid, and which would result in lpcraft trying to install `golang-[1.18]`...
