az aks use-dev-spaces create .bash_profile cause .profile not load

**Describe the bug**
After I run `az aks use-dev-spaces -g RGName -n Name`, the `.bash_profile` is created.

```
source /etc/bash_completion.d/azds
```

These are two common files `.profile` and `.bash_profile` in bash environment, but only one file will be applied. The `.bash_profile` is first priority. But in WSL, only `.profile` exists by default.

For example, in my box, I don't have a `.bash_profile` by default. All my profile settings are write in `.profile` file. After run `az aks user-dev-spaces` command, the `.bash_profile` been created. After I re-open WSL again, the `.profile` file is ignored because there is a `.bash_profile` file exist.

**To Reproduce**
`az aks use-dev-spaces -g RGName -n Name` under WSL.

**Expected behavior**
If there is a `.profile` file, use this one. If there is already has a `.bash_profile`, then use `.bash_profile`.
