docs: add avoid keyboard keyword, update SEO keywords, fix flaky docs e2e tests (#425)

## 📜 Description

Added `avoid keyboard` to keywords + updated SEO keywords.

## 💡 Motivation and Context

When I do search for `avoid keyboard react native` on `npm` the
`react-native-keyboard-controller` is not showing up in the search
results:

So this PR fixes this 🙃 

## 📢 Changelog

### Docs

- added `avoid keyboard` to `keywords` in `package.json`;
- updated SEO keywords;
- fixed flaky e2e test (exclude a picture from blogpost);

There is no way to test these changes - can be verified only after merge
+ publishing.

## 📸 Screenshots (if appropriate):

🤷‍♂️ 

## 📝 Checklist

- [x] CI successfully passed
- [x] I added new mocks and corresponding unit-tests if library API was
changed

 Fortunately this library is backward compatible with old architecture and will be compiled conditionally depending on which architecture you are using. So don't be afraid of updating it to the latest version - it doesn't have any breaking changes!
