SparseDiffTools broken w/ Julia 1.8.5

[DrStiev]

The Zygote extension in the current version of SparseDiffTools (v2.4.0) cause LoadError when used with Julia 1.8.5:

MWE:

• Project.toml

[deps]
Zygote = "e88e6eb3-aa80-5325-afca-941959d7151f"
SparseDiffTools = "47a9eef4-7e08-11e9-0b38-333d64bd3804"

• Loading

┌ Warning: Error requiring Zygote from SparseDiffTools
│ exception =

Seems the error is caused by the import statement
