Importing cuML`s UMAP before bertopic leads to FileNotFoundErrors

Nobody has claimed this yet.

# Overview:

Running `from bertopic import BERTopic` after importing cuML's UMAP gives a `FileNotFoundError`. Essentially, it is looking for `numba==0.56.1`, which is not installed on my system. Re-running the same code block fails multiple times, each time looking for a different not-installed package, until it finally succeeds, with no distinguishable poor results after success.

This could also be an issue on UMAP's end, not on BERTopics, but there is some overlap. Especially when I want to use cuML's UMAP and not the native UMAP (which is when this happens).

# MVE

The MVE is found [here](https://colab.research.google.com/drive/1H3I2cwpnnK8UHdy6aVj76FAxNKQ_RR8V?usp=sharing).

# Why this happens:

I'm not 100% sure on this one. What I think is going on is that, while importing the BERTopic class, the `bertopic/_bertopic.py` file calls `from umap import UMAP`, which is the line that's failing. This issue does *not* occur when just running `from bertopic import BERTopic` (without importing cuML`s UMAP). Could it be that there's some dependency conflicts with those two?

Note: this also does not happen for cuML's HDBSCAN, just UMAP. Could that be because BERTopic is importing `import hdbscan` instead of `from hdbscan import HDBSCAN`?

The error occurs multiple times until it finally goes away (and who said just re-running the code doesn't work!). Here are the errors in order:

```python
FileNotFoundError: [Errno 2] No such file or directory: '/usr/local/lib/python3.10/dist-packages/numba-0.56.4.dist-info/METADATA'
FileNotFoundError: [Errno 2] No such file or directory: '/usr/local/lib/python3.10/dist-packages/scikit_learn-1.2.2.dist-info/METADATA'
FileNotFoundError: [Errno 2] No such file or directory: '/usr/local/lib/python3.10/dist-packages/llvmlite-0.39.1.dist-info/METADATA'
```

# Possible solution:

Figure out whether the user has imported native umap or cuML's umap, then import that one in the `bertopic/_bertopic.py` file. Installing those specific versions that umap is looking for runs into dependency errors.

# Workarounds:

Continually re-run `from bertopic import BERTopic` until it works. This is obviously a bad solution, but I have the following code locally:

```python
while True:
try:
from bertopic import BERTopic
break
except FileNotFoundError:
continue
except Exception as e:
print(e)
break
```

Reproduce the linked Colab MVE with cuML's UMAP imported before BERTopic. Inspect bertopic/_bertopic.py at the `from umap import UMAP` import and compare it with the reported dependency behavior; done means BERTopic imports without the repeated FileNotFoundError in that setup.
