React Native SDK, installation guide fix

[github-actions]

In the provided code:

1. There is an extra closing </h1> tag after the <h4> tag, which should be removed.
2. The <div> tag is not opened properly and seems unnecessary. It should be removed.
3. It looks like there is a typo in the text Build PUSH features into their DApps, where PUSH should be replaced with Push.
4. In the postinstall script in the package.json file, the values of crypto,assert,url,stream,events,http,https,os,url,net,fs should not repeat url, and assert is not required in that list.
5. In the import statement for WebViewCrypto in the app root, the module path should be '@pushprotocol/react-native-sdk' instead of 'react-native-webview-crypto'.
6. The link to the restapi documentation seems incorrect. It should point to the correct location. The current link is https://github.com/push-protocol/push-sdk/blob/main/packages/restapi/README.md#sdk-features.
7. The Discord link in the contributing section seems broken. It should be corrected.
8. In the License section, the link should be corrected to the license file location.

After addressing these issues, the code seems structured and formatted correctly.

All looks good.

In the HTML code provided, I can see a few issues:

1. The second closing </h1> tag after the social media icons should be corrected (</div> should be used instead of </h1>).
2. There is a random </h1> tag after the block of social media icons which should be removed as it is unnecessary.

Other than that, the content seems to be structured correctly and there are no major issues.

Overall, the changes needed are minor, and the code is well-structured.

Here are the corrected sections:
