feature: Update teams-channel-picker to fluent UI designs (#1805)

* update: Set rtl and images for fluent UI look

* update: Make card height wrap around the content

* update: Make searched channels expand in dropdown

* refactor: Remove deprecated even.keyCode for event.code

* fix: Apply auto card height on the fluent-card

* fix: Set render direction to ltr by default and auto height card

* update: set the dir attribute at the top most part of the element

This together with setting the dir attribute on the fluent-tree-view enables
the fluentui components to set the dir on their own. Multiple dir attributes are
unnecessary and cause the fluentui components to exhibit unexpected behaviour.

* update: Change the usage of fluentui components

* update: Set card width

* update: Set the width to 368px

* update: Handle enter keypress on channel

* fix: use min-width to allow growth of element when txt is long

* fix: flexible width for the dropdown and selected values

* fix: hide the dropdown on losing component focus

* fix: change the loading component props to align with main component

* refactor: remove unused code

* fix: format fixes and new lock file

* fix: disable input on selecting a channel

* fix: toggle the chevrons and close btn correctly

* fix: set a fixed width and resize selected channel img

* fix: truncate selected team or channel to fit the width

* fix: test the fluent component in spinner

* fix: custom event detail should be an obj in an array

* fix: mark a channel selected by ID as highlighted in the DOM

* fix: remove the click event on the team tree-item

* fix: remove highlight on clicking a team name

- make clicking the team only expand/collapse channel list

* fix: stop showing the  previously selected channel

* remove the DOM properties that show it selected manually to avoid reloading the state of the component

* fix: selectionChanged evt to emit correct type

* fix: update the layout of selected pills

* fix: remove end slot on selected team

Render the team parent name with the default slot
