Bump react-native-webview to version 11.26.1

[fluiddot]

After upgrading the libraries to use Android API 33, the library react-native-webview couldn't be published due to a build error (reference):

/workdir/node_modules/react-native-webview/android/src/main/java/com/reactnativecommunity/webview/RNCWebViewManager.java:275: error: cannot find symbol
        view.getSettings().setAppCachePath(ctx.getCacheDir().getAbsolutePath());
                          ^
  symbol:   method setAppCachePath(String)
  location: class WebSettings
/workdir/node_modules/react-native-webview/android/src/main/java/com/reactnativecommunity/webview/RNCWebViewManager.java:277: error: cannot find symbol
        view.getSettings().setAppCacheEnabled(true);
                          ^
  symbol:   method setAppCacheEnabled(boolean)
  location: class WebSettings
/workdir/node_modules/react-native-webview/android/src/main/java/com/reactnativecommunity/webview/RNCWebViewManager.java:281: error: cannot find symbol
      view.getSettings().setAppCacheEnabled(false);
                        ^
  symbol:   method setAppCacheEnabled(boolean)
  location: class WebSettings
/workdir/node_modules/react-native-webview/android/src/main/java/com/reactnativecommunity/webview/RNCWebViewManager.java:475: error: cannot find symbol
    view.getSettings().setAppCacheEnabled(false);
                      ^
  symbol:   method setAppCacheEnabled(boolean)
  location: class WebSettings

On Android 13, setAppCacheEnabled function is deprecated. This was already solved in the library (react-native-webview/react-native-webview#2547), so we can simply bump the library to the latest 11 version to address the issue. Seems there are no breaking changes between 11.6.2 to 11.26.1.

NOTE: As mentioned here, we keep using version 11 as version 12 is not working properly.
