Better Zoom Webapp Support for meeting links (#1542)

* Support for exec and mime types. Zoom integration

In order to better support webapp zoom:
  - Added optional params for omarchy-webapp-install
    - exec, defaults to omarchy-launch-webapp
    - mimetypes, defaults blank
  - added zoom webapp launcher that parses meeting links and transforms
them and calls launch webapp to join meeting links
  - migration to convert existing zoom installs to the new custom
handler
  - updated the base installer to call new zoom handler and set
mimetypes

* default should be in the else

* Add new line at end of file

* Missed new line on migration

* Updated conditionals to be a little more clean

* This is a rare setup so let's just save it for the direct CLI

* Use new bash conditionals

* Rename to fit under the existing namespace of cmds

* Fix after merge

* Use new syntax and add missing segment comments

* Cleanup a bit

* Use local icon for zoom with migration

* Fix regexp

* Refer to raw local icon references
