CI: remove no-longer-available conda versions
closes #15214, remove bottleneck < 1.0.0
changes CI min of xlsxwriter to 0.5.2

removing our ``pandas`` channel as well (which held some really old versions of things).
seems conda simply 'removed' old versions of packages (xlsxwriter 0.4.6 and bottleneck 0.8.0). They are pretty old so adjusting the CI. # [Codecov](https://codecov.io/gh/pandas-dev/pandas/pull/17142?src=pr&el=h1) Report

there are some problems with conda-forge at the moment, so it might also be you are running in similar things (https://github.com/Anaconda-Platform/support/issues/126- Ah, you already opened an issue :-) yeah I think I fixed some of the older packages issues, but this is an odd one.
