LSDW cfg incorrect

[here](https://github.com/bigtreetech/LIS2DW/blob/master/Firmware/sample-bigtreetech-lis2dw-v1.0.cfg)
it says btt_adxl when it should be like so.

[lis2dw]
cs_pin: btt_lis2dw:gpio9
#spi_bus: spi1a
spi_software_sclk_pin: btt_lis2dw:gpio10
spi_software_mosi_pin: btt_lis2dw:gpio11
spi_software_miso_pin: btt_lis2dw:gpio8
axes_map: -y,x,-z

[resonance_tester]
probe_points: 100, 100, 20
accel_chip: lis2dw

Open Firmware/sample-bigtreetech-lis2dw-v1.0.cfg and compare its sensor and resonance-tester sections with the configuration shown in the issue. Check the naming and pin entries against the reported lis2dw configuration; done means the sample no longer refers to btt_adxl where the issue identifies an incorrect reference.
