UX update for context create and context use to list plugins will be installed

[chandrareddyp]

What this PR does / why we need it

Before this change, the tanzu context create context-name and tanzu context use context-name commands created and activated the given context and installed the required plugins. However, they did not list all the plugins they would install as part of the command execution, resulting in a suboptimal user experience. Users were unaware of how many plugins would be installed or which ones were included. Sometimes, the installation process took a considerable amount of time, leaving users in the dark about the installation progress.

After this PR, the tanzu context create context-name and tanzu context use context-name commands will list the plugins they are going to install. This enhancement provides a great user experience, as users will know in advance which plugins are being installed. This makes it easier for users to track the progress.

1. I was curious if we wanted to do the same for tanzu context create?
   2.SyncPluginsForContextType is no longer used anywhere

1. I was curious if we wanted to do the same for tanzu context create?
   2.SyncPluginsForContextType is no longer used anywhere

SyncPluginsForContextType is not being used anywhere!

So why are we keeping that function if it is not used?

[marckhouzam]

Another very nice improvement. Thanks!

1. Please add some release notes in the PR description.
2. I still think doing this change for tanzu context create is just as important. I think it is a one line change? What do you think

SyncPluginsForContextType

Removed it.
