Hello @tmc, wanted to see if this could be reviewed in short order. I currently use chroma-go outside of langchaingo, which has caused a version dependency. Also, this change brings chroma-go and langchaingo in-line api wise.

I can confirm that this commit is safe and does indeed resolve the issue. Tested by adding the following directive in my go.mod:

replace github.com/tmc/langchaingo => github.com/dddbliss/langchaingo v0.1.5-0.20240210073700-9ac0e7441c4d

and then rebuilding and running my project.

this might more appropriately be a TODO as we might want to accept ctx in this method, but this is fine. Thanks.
