More defaults need to be set

[Dr-Irv]

In #1293, @yangdanny97 added default values for many of the pandas methods and functions.

Recent PRs in #1315 and #1316 have revealed that a few functions were missed by his methodology for generating the defaults:

• interval_range
• read_sql
• concat
• read_table
• read_csv

@yangdanny97 can you look at your script and see why you missed those functions and also check if others were not missed as well?

@MarcoGorelli has made some improvements to the scripts, which are now open sourced at https://github.com/yangdanny97/docs2types, perhaps we can re-run the script and make a new PR?
