Keep length of PAT stable (#5374)

#### What type of PR is this?

/kind improvement
/area core
/milestone 2.13.x

#### What this PR does / why we need it:

In fact, PAT is a JWT, which is very long. However, we put the claim `roles` into PAT, which will cause the length of PAT to increase as the `roles` information increases.

So, the current PR removes the claim `roles` from PAT, which ensures that the length of PAT becomes stable and we can update roles information for PAT at runtime.

#### Which issue(s) this PR fixes:

Fixes https://github.com/halo-dev/halo/issues/5366

#### Does this PR introduce a user-facing change?

```release-note
避免个人令牌长度随着角色信息增长
