URL: https://github.com/apache/apisix/issues/9904
### Description
When I set up a public-api plugin in a normal route, the route goes back
directly to the 404
my steps:
1.set route config:
```
{
"id": "471122704460677830",
"create_time": 1690340614,
"update_time": 1690348433,
"uri": "/apisixtest/*",
"name": "apisix_test",
"priority": 12,
"methods": [
"GET",
"POST",
"PUT",
"DELETE",
"PATCH",
"HEAD",
"OPTIONS"
],
"plugins": {
"proxy-rewrite": {
"regex_uri": [
"^/apisixtest(/|$)(.*)",
"/$2"
]
}
},
"upstream": {
"nodes": [
{
"host": "192.168.88.66",
"port": 9081,
"weight": 1
}
],
"retries": 2,
"timeout": {
"connect": 6,
"send": 6,
"read": 6
},
"type": "roundrobin",
"scheme": "http",
"pass_host": "pass",
"keepalive_pool": {
"idle_timeout": 60,
"requests": 1000,
"size": 320
},
"retry_timeout": 2
},
"status": 1
}
```
Normal access:

2.update the route ,add the public-api:
```
{
"id": "471122704460677830",
"create_time": 1690340614,
"update_time": 1690348814,
"uri": "/apisixtest/*",
"name": "apisix_test",
"priority": 12,
"methods": [
"GET",
"POST",
"PUT",
"DELETE",
"PATCH",
"HEAD",
"OPTIONS"
],
"plugins": {
"proxy-rewrite": {
"regex_uri": [
"^/apisixtest(/|$)(.*)",
"/$2"
]
},
"public-api": {
"disable": false,
"url": "/apisix/plugin/jwt/sign"
}
},
"upstream": {
"nodes": [
{
"host": "192.168.88.66",
"port": 9081,
"weight": 1
}
],
"retries": 2,
"timeout": {
"connect": 6,
"send": 6,
"read": 6
},
"type": "roundrobin",
"scheme": "http",
"pass_host": "pass",
"keepalive_pool": {
"idle_timeout": 60,
"requests": 1000,
"size": 320
},
"retry_timeout": 2
},
"status": 1
}
```

Where is the problem, is it the wrong way to use it?
