feat(git): check semver tags

[LEI]

Description

As well described in #1729, a way to detect outdated pinned plugins is check_pinned but doesn't help much for semver ranges. This change adds a check_tags option under checker to mark plugins as outdated if their last tag differs.

This could be improved to show the new tag but I am not sure how to render it and this works for me as is.

Configuration:

require('lazy').setup({
  checker = {
    enabled = true,
    check_tags = true,
  },
})

Example plugin:

{
  'stevearc/overseer.nvim',
  version = 'v1.x',
  opts = {},
}
