fix bad f-string placement on describe_one_table_details

[saucoide]

Description

The string is split in 2 and and concatenated implicitly, but the f-string is applied only to the first one, which has no variables to replace, while the second one does and inserts a literal {oid}

this is breaking \d on patterns with a pg syntax error e.g:

\d mytabl*
