feat(gnss_poser): use header.frame_id as gnss_frame

[KYabuuchi]

Description

This PR resolves #6108

• Removed gnss_frame which indicates antenna's frame_id from parameters.
• Changed to identify the antenna's frame_id by referencing nav_sat_fix.header.frame_id.

(Please note the header.frame_id in NavSatFix indicates the frame_id of the antenna, not the Earth or ellipsoid. See also https://docs.ros.org/en/noetic/api/sensor_msgs/html/msg/NavSatFix.html)

Tests performed

I have tested rosbag-replay-simulation in tutorial, and confirmed that the following warnings are not printed.

[gnss_poser-32] [WARN 1705543736.053584803] [sensing.gnss.gnss_poser]: "gnss" passed to lookupTransform argument source_frame does not exist.
[gnss_poser-32] [WARN 1705543736.053649454] [sensing.gnss.gnss_poser]: Please publish TF base_link to gnss

Effects on system behavior

Basically, this PR does not change the system behavior.

If header.frame_id of nav_sat_fix is not set correctly, gnss_poser outputs antenna position instead of base_link position.
(However, since this output is only used for initial position estimation, this is not a critical problem.)
