Webkit returns additional new line character with element.innerText

Nobody has claimed this yet.

**Describe the bug**
When using Get Text keyword using Webkit there's an additional new line character in the returned text. This has been reported to Playwright (https://github.com/microsoft/playwright/issues/7698 and https://github.com/microsoft/playwright/issues/5478) where suggestion is to use element.textContent instead.

If I'm not mistaken Get Text keyword returns element.innerText (https://github.com/MarketSquare/robotframework-browser/blob/6a5116dd5a45b74938997618c67ac0fe94b49e49/node/playwright-wrapper/getters.ts#L104). I know this is a Webkit specific issue but I'd be interested to know what is the reason for use of innerText? Element.textContent would fix this (for us) but there's probably a good reason to use innerText?

**To Reproduce**
Steps to reproduce the behavior:
1. Set HTML content foo
2. ${text} = Get Text id=important
3. On Chromium and Firefox ${text} == "foo"
4. On Webkit ${text} == "foo\n"

**Expected behavior**
I would expect the text content to be the same on Chromium, Firefox and Webkit.

**Additional context**
-

Start at node/playwright-wrapper/getters.ts around the linked Get Text implementation; reproduce the button and span case on Chromium, Firefox, and WebKit and inspect the existing getter tests. Done means the selected behavior is covered by a regression test and Get Text returns the agreed, consistent value across these browsers.
