feat(sagemakerunifiedstudio): Wire connection credentials provider and bug fixes (aws#2196)

## Problem
This PR addressing following problems:
1. Handle rendering s3 access grant node
2. Implement client store to create separate clients for different
connections
3. Fix rendering s3 table catalog in Lakehouse node
4. Wire connection credentials provider and bug fixes
5. Adapt connection credentials provider for private model clients
(sqlworkbench, gluecatalog)
6. UX: move all s3 nodes under "Buckets" folder

Rev 2:
1. Addressed comments
2. bug fixes

## Solution
1. Handle rendering s3 access grant node
`createS3AccessGrantNodes` in `sagemakerUnifiedStudioDataNode.ts` and
`s3Strategy.ts`

3. Implement client store to create separate clients for different
connections
`src/sagemakerunifiedstudio/shared/client/clientStore.ts`

4. Fix rendering s3 table catalog in Lakehouse node
`src/sagemakerunifiedstudio/explorer/nodes/lakehouseStrategy.ts`

5. Wire connection credentials provider and bug fixes
Involving all strategy files and client files

6. Adapt connection credentials provider for private model clients
(sqlworkbench, gluecatalog)
`src/sagemakerunifiedstudio/shared/client/credentialsAdapter.ts`

7. UX: move all s3 nodes under "Buckets" folder
`src/sagemakerunifiedstudio/explorer/nodes/s3Strategy.ts`
