Subject: [PATCH] [platform][arista] Fix NVMe sensor chip address in
 sensors.conf for 7060X6-64PE-B

     Please provide the following information:

#### Why I did it
The `sensors.conf` file was referencing a non-existent NVMe PCI address (`nvme-pci-0500`) on the Arista-7060X6-64PE-B platform. This mismatch caused `pmon#sensord` to report repeated I/O errors while attempting to read sensor data for a non-existent device (`nvme/#7`). Updating the config to use the correct PCI address (`nvme-pci-0400`) resolves the issue.

##### Work item tracking
- Microsoft ADO **(number only)**: 32849896

#### How I did it
Modified `sensors.conf` to change the chip identifier from `nvme-pci-0500` to `nvme-pci-0400` to match the actual hardware PCI bus location.

#### How to verify it

<!--
If PR needs to be backported, then the PR must be tested against the base branch and the earliest backport release branch and provide tested image version on these two branches. For example, if the PR is requested for master, 202211 and 202012, then the requester needs to provide test results on master and 202012.
-->
- Verified that the `/dev/nvme*` devices are present and functional
- Confirmed correct PCI ID using `lspci`

- Edited `sensors.conf` and restarted `pmon` (`systemctl restart pmon`)
- Monitored logs to ensure `pmon#sensord` no longer reports I/O errors for `nvme/#7`
