[CARBONDATA-4269] Update url and description for new prestosql-guide.md
Why is this PR needed?
PrestoSQL has now changed its name to Trino. Because Facebook established
the Presto Foundation at The Linux Foundation®，Led to prestosql Must be change
the name
More information can see here :
https://trino.io/blog/2020/12/27/announcing-trino.html
What changes were proposed in this PR?
1. Change the url to prestosql 333
2. Added a description indicating that the user prestoSQL has been renamed
to Trino
Does this PR introduce any user interface change?
No
Is any new testcase added?
No
This closes #4202

that spark also connects to same metastore db for creating tables and updating
