fix: skip processing of Squiz.Commenting.FunctionComment for @inheritDoc

[PavelSavushkinMix]

It's supported to use {@inheritdoc}. Add support of @inheritdoc (w/o brackets).
Original PR number - #3051

Closes #2770

[jrfnl]

For context:

phpDocumentor states that inheritance is implicit when there is no docblock, so the tag should only be used for partial inheritance via an inline tag {@inheritDoc}

Refs:

• https://docs.phpdoc.org/3.0/guide/guides/inheritance.html
• https://docs.phpdoc.org/3.0/guide/references/phpdoc/inline-tags/index.html#inline-tag-reference

The draft PSR-19 reference does allow for the tag without brackets, but then again, is still subject to change as still in draft.

So, @jrfnl, would you like me to close the PR due to provided references?

Or just keep it till the PSR-19 is released?

Not really up to me. I added the references so the maintainer can make an informed decision.

I'd say, leave it open for now and wait for a response from someone with commit rights.
Be aware that it may be a while before you will get such a response.,
