Issue:
`Map.rotate` does not update `NAXISi` fields in the metadata
### Describe the bug

`resample()`, `submap()`, and `superpixel()` all update NAXISi, but `rotate` does not.

### To Reproduce

```python
from sunpy.map import Map, GenericMap
import astropy.units as u

# Prints the shape of the data array, and the naxis fields
def print_metadata_and_shape(label: str, map: GenericMap):
    print(f"---{label}---")
    print(f"Shape: {map.data.shape}")
    print(f"Naxis: ({map.meta["NAXIS1"]}, {map.meta["NAXIS2"]})")

# Using a helioviewer jp2 since you can't write a fits file out as jp2
# and read it back (different issue).
aia_map = Map("https://helioviewer.org/jp2/AIA/2024/03/12/304/2024_03_12__00_00_05_130__SDO_AIA_AIA_304.jp2")
print_metadata_and_shape("Original map", aia_map)

# Rotate the image and print info
aia_rotated = aia_map.rotate(45 * u.deg, missing=0)
print_metadata_and_shape("Rotated map", aia_rotated)

# Save rotated image
aia_rotated.save("aia.fits")
aia_rotated.save("aia.jp2")

# Read back rotated fits and look at metadata
aia_fits_readback = Map("aia.fits")
print_metadata_and_shape("FITS Readback", aia_fits_readback)

# Read back rotated jp2 and look at metadata
aia_jp2_readback = Map("aia.jp2")
print_metadata_and_shape("JP2 Readback", aia_jp2_readback)

```

Output from above code:
```
---Original map---
Shape: (4096, 4096)
Naxis: (4096, 4096)
---Rotated map---
Shape: (5794, 5794)
Naxis: (4096, 4096)
---FITS Readback---
Shape: (5794, 5794)
Naxis: (5794, 5794)
---JP2 Readback---
Shape: (5794, 5794)
Naxis: (4096, 4096)
```
