fix(core): filters emojipicker on label in addition to tags (#15129)

Fixes #15116 
# Issue
Emojipicker keyword filtering only filtered on `tags`, and not `label`.
So searching for an emoji's name would not result in said emoji ending
up in the result. E.G. searching "sunflower" does not make 🌻 appear

# Solution
Adding an extra condition to the filter function to check if the keyword
is a substring of an emoji's label

# Result
Search results now include emojis with that `label`

## Summary by CodeRabbit

* **New Features**
* Improved emoji picker search to include matches on both emoji labels
and tags (case-insensitive), enabling broader search results for better
discoverability.
