Add --follow-symlinks flag to glob command (fixes #15559) (#15626)
Fixes #15559

# Description
The glob command wasn't working correctly with symlinks in the /sys
filesystem. This commit adds a new flag that allows users to explicitly
control whether symlinks should be followed, with special handling for
the /sys directory.

The issue was that the glob command didn't follow symbolic links when
traversing the /sys filesystem, resulting in an empty list even though
paths should be found. This implementation adds a new
`--follow-symlinks` flag that explicitly enables following symlinks. By
default, it now follows symlinks in most paths but has special handling
for /sys paths where the flag is required.

Example:
`
# Before: This would return an empty list on Linux systems
glob /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor

# Now: This works as expected with the new flag
glob /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
--follow-symlinks
`

# User-Facing Changes

1. Added the --follow-symlinks (-l) flag to the glob command that allows
users to explicitly control whether symbolic links should be followed
2. Added a new example to the glob command help text demonstrating the
use of this flag

# Tests + Formatting

1. Added a test for the new --follow-symlinks flag
