1. Add server mode status to -V option …

   When YJIT (disabled by default) is enabled in Ruby, it is displayed as follows.
   
   ```console
   % ruby --yjit -ve 'RubyVM::YJIT.enabled?'
   ruby 3.2.0dev (2022-08-18T08:09:08Z master b0b9f7201a) +YJIT [x86_64-darwin19]
   ```
   
   `+YJIT` is added when YJIT is enabled.
   
   This is a change inspired by it. Below is before and after `rubocop -V`.
   
   ## Before
   
   ```console
   % rubocop -V
   1.35.0 (using Parser 3.1.2.1, rubocop-ast 1.21.0, running on ruby 3.2.0 x86_64-darwin19)
     - rubocop-performance 1.14.3
     - rubocop-rake 0.6.0
     - rubocop-rspec 2.11.1
   ```
   
   ## After
   
   It makes the `-V` format like `ruby --version`.
   
   ### No server mode
   
   The platform (`x86_64-darwin19`) display will change slightly.
   
   ```console
   % rubocop -V
   1.35.0 (using Parser 3.1.2.1, rubocop-ast 1.21.0, running on ruby 3.2.0) [x86_64-darwin19]
     - rubocop-performance 1.14.3
     - rubocop-rake 0.6.0
     - rubocop-rspec 2.11.1
   ```
   
   ### Server mode
   
   `+server` is added when server is enabled.
   
   ```console
   % rubocop -V
   1.35.0 (using Parser 3.1.2.1, rubocop-ast 1.21.0, running on ruby 3.2.0) +server [x86_64-darwin19]
     - rubocop-performance 1.14.3
     - rubocop-rake 0.6.0
     - rubocop-rspec 2.11.1
   ```
   
   This change has the following benefits:
   
   - Shorthand alternative to `rubocop --server-status`
   - We can check the enable or disable of server mode in the bug report template
