quote.d: fix indentation of generated paragraphs

quote.d was missing a .IP at the end which caused the paragraphs
generated for See-also, Multi, and Example to not be indented correctly.

I also remove a redundant "This option can be used multiple times.", and
replaced .IP "item" with .TP .B "item" to make more clear which lines
are part of the list of commands and which aren't.

Closes curl#11371

 You must send syntactically correct FTP commands as RFC 959 defines to FTP
 servers, or one of the commands listed below to SFTP servers.

 SFTP is a binary protocol. Unlike for FTP, curl interprets SFTP quote commands
 itself before sending them to the server. File names may be quoted
 shell-style to embed spaces or special characters. Following is the list of
 all supported SFTP quote commands:
 .RS
-.IP "atime date file"
+.TP
+.B "atime date file"
 The atime command sets the last access time of the file named by the file
 operand. The <date expression> can be all sorts of date strings, see the
 *curl_getdate(3)* man page for date expression details. (Added in 7.73.0)
-.IP "chgrp group file"
+.TP

 The chgrp command sets the group ID of the file named by the file operand to
 the group ID specified by the group operand. The group operand is a decimal

 mode operand is an octal integer mode number.

 user ID specified by the user operand. The user operand is a decimal

 The ln and symlink commands create a symbolic link at the target_file location
 pointing to the source_file location.
