Function names updated incorrectly when containing `ID`

### What happened?

Change to `wordWalker` in `v0.17.55` unexpectedly changed all the `LT`/`EQ` function names if they contained `ID`

For example:

previous version correctly capitalized the `G` and `L` in these: (`v0.17.54`)

```
OwnerIDGt *string `json:"ownerIDGT,omitempty"`
OwnerIDGte *string `json:"ownerIDGTE,omitempty"`
OwnerIDLt *string `json:"ownerIDLT,omitempty"`
OwnerIDLte *string `json:"ownerIDLTE,omitempty"`
```

With the `v0.17.55` version they are lowercased
```
OwnerIdgt *string `json:"ownerIDGT,omitempty"`
OwnerIdgte *string `json:"ownerIDGTE,omitempty"`
OwnerIdlt *string `json:"ownerIDLT,omitempty"`
OwnerIdlte *string `json:"ownerIDLTE,omitempty"
```

This looks to be due to https://github.com/99designs/gqlgen/pull/3302/files

### What did you expect?

Functions correctly capitalized when containing the `ID`

### Minimal graphql.schema and models to reproduce

Adding the following test to `template_test.go:ToGo`:

```
require.Equal(t, "OwnerIDGT", ToGo("OwnerIDGT"))
```

```
Error Trace: /Users/sarahfunkhouser/go/src/github.com/golanglemonade/gqlgen/codegen/templates/templates_test.go:59
Error: Not equal:
expected: "OwnerIDGT"
actual : "OwnerIdgt"
```

### versions
- `go run github.com/99designs/gqlgen version`? v0.17.55
