feat(var-naming): deprecate and gracefully translate skip option

[chaimleib]

Motivation

PR mgechev#1603 fixes mgechev#1602, but breaks the skipPackageNameCollisionWithGoStd option. This PR gracefully handles the situation and warns the user about the deprecation.

Manual testing

All the below tests start from this basic state. Create a folder named http like so:

http/
    http.go
    revive.toml

http.go

# Package http contains helpers.
package http

revive.toml

enableAllRules = false

[rule.var-naming]
  arguments = []

Build revive:

$ cd path/to/revive
$ make build

Navigate to the http folder:

$ cd path/to/http

Empty arguments

$ path/to/revive/revive .
$ ls
http.go  revive.toml

No errors, just like golint.

Debug mode, empty arguments

$ DEBUG=y path/to/revive/revive .
time=2025-12-04T17:25:43.528-07:00 level=INFO msg="Logger initialized" logFile=revive.log
time=2025-12-04T17:25:43.528-07:00 level=INFO msg="Config loaded" rules=[var-naming]

$ ls
http.go  revive.log  revive.toml

$ cat revive.log
time=2025-12-04T17:25:43.528-07:00 level=INFO msg="Logger initialized" logFile=revive.log
time=2025-12-04T17:25:43.528-07:00 level=INFO msg="Config loaded" rules=[var-naming]

The command creates revive.log. No errors, just INFOs.
