Intent filter elements are not merged properly between feature modules and base modules

[BenSchwab]

Describe the bug
Intent filter elements are not merged from between a dynamic feature manifest and base feature manifest.
I believe this is because there is a typo in AndroidManifest.java: https://github.com/google/bundletool/blob/master/src/main/java/com/android/tools/build/bundletool/model/AndroidManifest.java#L76
public static final String INTENT_FILTER_ELEMENT_NAME = "intent-filder"; should be
public static final String INTENT_FILTER_ELEMENT_NAME = "intent-filter";

Bundletool version(s) affected
1.9.0

Stacktrace
N/A

To Reproduce
Create a dynamic feature with a manifest for an activity that contains an intent filter. In the base apk create a manifest entry for the same activity with the same intent filter.

Note that a universal apk only contains the intent-filter from the dynamic feature module.

Expected behavior
Universal apk should have the intent-filters from the base module and the dynamic feature module.

Known workaround
N/A

Environment:
OS: [e.g. iOS 10.3.3]
