Adding 2 snippets: add basemapStyle and adding 4.19 to getAPI

[hhkaos]

I just wanted to do my first contribution to this project adding two very basic snippets 😄

In conclusion:

• remove the importESM snippet (keep the basemap snippet)
• update the release number

@kellyhutchins can you make a new release after UC or whenever you have a bit of time?

[RalucaNicola]

I updated the comment because I thought Raul can also update the release number :D

[hhkaos]

Thanks @RalucaNicola, done!.

About the release number I wasn't sure what to add so I did this -> UPDATE: I did this

[kellyhutchins]

Thanks for the contribution! I am going to work on cleaning up a few of my older snippets and get the extension republished later this week.
