Can't run docs/source/notebooks/glayout/GLayout_Cells.ipynb

1. The Run in Colab link points to a different file.
2. glayout is not loaded as a module, which causes an error in 1.3. Importing Libraries and Utility Functions

ModuleNotFoundError: No module named 'glayout.pdk.sky130_mapped'

3. Creating link to glayout in step 1.1 as below, loads the module.

!ln -s OpenFASOC/openfasoc/generators/gdsfactory-gen/glayout .

4. This results in a different error `sky130_mapped_pdk.cell_decorator_settings.cache=False` where `cell_decorator_settings` does not have the `cache` object.

This may be due to the removal of the assignment in `openfasoc/generators/gdsfactory-gen/glayout/pdk/mappedpdk.py`

def from_gf_pdk(
    cls,
    gfpdk: Pdk,
    **kwargs
):

...

passargs["cell_decorator_settings"]=gfpdk.cell_decorator_settings

Removing the line causing the error, results in other errors. Maybe there's an older version that works?

Ok. So during the first installation, there was this message

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
gf180 0.1.0 requires gdsfactory<7.17,>=7.16.0, but you have gdsfactory 7.7.0 which is incompatible.
sky130 0.10.1 requires gdsfactory==7.16.0, but you have gdsfactory 7.7.0 which is incompatible.

So I bumped the gdsfactory version to 7.16.0 which seems to have broken everything.

glayout is not loaded as a module, which causes an error in

This is probably because the installation steps seem to be missing a cd step. ~I'll make PR fixing this soon.~ (edit: I didn't notice #295)

Until then, can you try using the installation steps in the first cell of this notebook?
