Generated types incorrectly mark interval type as unknown

[icopp]

Bug report

• I confirm this is a bug with Supabase, not with my own application.
• I confirm I have searched the Docs, GitHub Discussions, and Discord.

Describe the bug

Interval columns aren't correctly inferred as strings.

To Reproduce

• Create a table with an interval column
• Run supabase gen types --lang=typescript --local
• See that the interval column is generated as unknown

Expected behavior

The interval column should be generated as string.

Screenshots

n/a

System information

• Version of supabase (not supabase-js): 2.20.5
• Version of Node.js: 22.12.0

Additional context

The format of the string depends on SET intervalstyle, but it's always a string.
