bugfix: Fix Issue with Path Quoting Update hubble.sh (#2426)

## Why is this change needed?

**Subject:** Fix Issue with Path Quoting in `source ~/.bashrc`

A bug in the script where the `~` symbol, which represents the user's
home directory, was not expanding properly.

Specifically, in the following code:

```bash
if [[ ! -f "~/.bashrc" ]]; then
  source ~/.bashrc
fi
```

The `~` should have been outside the quotes to properly expand it to the
full path. The corrected version is:

```bash
if [[ ! -f ~/.bashrc ]]; then
  source ~/.bashrc
fi
```
