[dependabot]

Bumps click from 8.4.1 to 8.4.2.

Changelog

Sourced from click's changelog.

Version 8.4.2

Unreleased

• Fix Fish shell completion broken in 8.4.0 by {pr}3126. Newlines and tabs in option help text are now escaped, keeping the original completion format while still supporting multi-line help. {issue}3502 {issue}3043 {pr}3504 {pr}3508
• Deprecated commands and options with empty or missing help text no longer render a stray leading space before the (DEPRECATED) label. {pr}3509
• A {class}Group with invoke_without_command=True marks its subcommand as optional in the usage help, showing [COMMAND] instead of COMMAND. {issue}3059 {pr}3507
• echo_via_pager flushes after each write, so passing a generator streams output to the pager incrementally instead of staying hidden until the pipe buffer fills. {issue}3242 {issue}2542 {pr}3534
• echo_via_pager and get_pager_file no longer close a borrowed stdout stream when no external pager runs, completing the partial I/O operation on closed file fix from {pr}3482. {issue}3449 {pr}3533
