Fail to validate a time value.

**What version of Ajv are you using? Does the issue happen if you use the latest version?**
`ajv: 8.18.0` and `ajv-formats: 3.0.1`
**Ajv options object**

```javascript
{allErrors: true}
```

**JSON Schema**

```json
{
"type":"object",
"properties":{
"time":{"type":["string","null"],"oneOf":[{"type":"string","format":"time"},{"type":"null"}]}
},
"required":[],
"additionalProperties":false
}
```

**Sample data**

```json
{time: "01:00:00"}
```

**Your code**

```javascript
import Ajv from 'ajv';
import addErrors from 'ajv-errors';
import addFormats from 'ajv-formats';

const ajv = new Ajv({allErrors: true});
addFormats(ajv);
addErrors(ajv);

const validate = ajv.compile(schema);
validate(sampleData);
```

**Validation result, data AFTER validation, error messages**

```
[
{
instancePath: '/time',
schemaPath: '#/properties/time/oneOf/0/format',
keyword: 'format',
params: { format: 'time' },
message: 'must match format "time"'
},
{
instancePath: '/time',
schemaPath: '#/properties/time/oneOf/1/type',
keyword: 'type',
params: { type: 'null' },
message: 'must be null'
},
{
instancePath: '/time',
schemaPath: '#/properties/time/oneOf',
keyword: 'oneOf',
params: { passingSchemas: null },
message: 'must match exactly one schema in oneOf'
}
]
```

**What results did you expect?**
`validate` function should return `true`.
