[MINOR][INFRA][R] Show the installed packages in R in a prettier way

### What changes were proposed in this pull request?

This PR proposes to fix the AppVeyor configuration to show all installed R packages with name/versions.

**Before:**

```
[1] '1.29'
[1] '2.3'
[1] '2.3.2'
[1] '1.7.3'
[1] '3.2.3'
[1] '0.17.1'
```

**After:**

```
                  Package  Version
arrow               arrow   0.17.1
askpass           askpass      1.1
assertthat     assertthat    0.2.1
backports       backports    1.1.8
base64enc       base64enc    0.1-3
bit                   bit 1.1-15.2
bit64               bit64    0.9-7
...
```

### Why are the changes needed?

To show the package versions in a prettier way, and don't update the line every time when a package is added.

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

No, dev-only.

### How was this patch tested?

AppVeyor CI should test it out.

Closes #29038 from HyukjinKwon/minor-appveyor.
