While reading INFORMATION_SCHEMA details on Snowflake documentation site URL Given below ; we can see 2 objects one is views and other is Table Functions. Views provide that database specific objects (Tables, Functions , stages etc ) metadata where as Table Functions can be used to return account level usages. When i browsed though Information Schema in each Databases i found only Views but not Table functions.
Have they moved these Table Functions

Your screenshot shows the "object browser" in the Snowflake WebGUI. In here you can only see views and tables, no table functions.

So... they are still there and you can execute them :-)
Edit: You can use
SHOW FUNCTIONS
to see all functions in your account.
