Unexpected zero value comparison operation error: binary literal has no digits

[gtk-grafana]

Describe the bug
Every comparison operation on a "duration" or "bytes" field requires a unit, except when the field is "bytes" and the value is 0.

To Reproduce
Steps to reproduce the behavior:

1. Run this query: {service_name=`loki/loki`} | json | logfmt | drop __error__, __error_details__ | throughput>=0B
2. Cry in the tub
3. (workaround) delete the unit

Expected behavior
Users might be using variables within grafana, or frameworks like scenes to build dynamic dashboards, as such, one would expect the same query to run with different numeric inputs without needing to adjust the units for specific cases.
So I would expect {service_name=`loki/loki`} | json | logfmt | drop __error__, __error_details__ | throughput>=0B, and {service_name=`loki/loki`} | json | logfmt | drop __error__, __error_details__ | throughput>=1B, to both be valid logQL, however the former throws the binary literal has no digits error.

I understand that the throughput>=0B is not a good filter, and the workaround is to drop the unit or change the filter to throughput!="", but imagine an application like Explore logs tries to create some UI for helping users write comparison operation filters, for every (duration/bytes) comparison a unit is required, and users might be fiddling with values in the UI, and instead of removing a filter, they change the value to 0 temporarily. Currently I'd need to either code in a unit-less filter for the 0 case, or remove the filter entirely, both of which could confuse the end-user. Also since I'm using a variable value to concatenate the users selection for unit with the value in the logQL output, removing the unit from the value will reset their unit selection, upsetting the users expectation that whatever unit they entered in the filter will persist in the future when they make edits

TL;DR: This query would run without error:
{service_name=`loki/loki`} | json | logfmt | drop __error__, __error_details__ | throughput>=0B | throughput <10GB

Not a high priority, but hopefully a quick fix.

Environment:

• Infrastructure: [e.g., Kubernetes, bare-metal, laptop]
• Deployment tool: [e.g., helm, jsonnet]
