Macro docs lack examples of arg() macro

[timofei-iatsenko]

While writing SWC Macro plugin and reading babel macro source code found this in tests:

export default [
  {
    name: "Arg macro should be exluded from values",
    input: `
        import { t, arg } from '@lingui/macro';
        const a = t\`Hello $\{arg('name')\}\`;
    `,
    expected: `
        import { i18n } from "@lingui/core";
        const a = 
          /*i18n*/
          i18n._("Hello {name}")
    `,
  },
]

Which is not described anywhere. Or if it's outdated - should be removed from codebase.

Looks like it's something old and outdated because typings also not exporting it. So it's better to remove it from codebase to avoid confusion.

@Martin005 @andrii-bodnar i'm going to delete this from codebase, the value of this feature is not clear, and it was not public anyway.

@thekip let's first ask @tricoder42 for more details, maybe there is some point here

[timofei-iatsenko]

It looks like an ad-hoc solution to avoid problems with escaping which we fixed recently.

@thekip agree with you

Hey guys, sorry for late response. I honestly don't recall the reason behind this feature, so feel free to remove it. Especially if it's obsolete.
